Hi Roger
I’m about to create this set up on my MacBook Pro (unibody 2.8GhZ Core 2 Duo).
If you just clone your current System to the SSD it will be too large.
I’ll describe below how to install from scratch and keep your library to a manageable size.
I’ve been researching it for a while now and I’m quite experienced at HD swapouts and system installs, so I’m hoping I know the steps to take.
(HDD means the internal Hard Disk Drive, SSD refers to the ExpressCard slot Solid State Drive).
I’m replacing the internal HDD with a larger, faster drive and adding a 48GB FileMate SSD in the ExpressCard slot to be the Startup drive.
The OS, Apps and system and library (without themes or templates installed by specific apps) will live on the SSD.
My home folder, and all files and media, plus themes and template from apps, will be stored on the internal HDD.
Obviously this will be a more useful post if I wait until after I’ve done the install successfully, but I can distill some of the stuff I’ve learned so far here if that helps…: (I’m waiting for the hardware to arrive, so it will be a few days before I do it myself)...
BEFORE YOU START
Clone your internal drive to an external drive. Obviously.
The easiest way is to use CarbonCopyCloner.
If you want to make a nice new clean install of your apps etc (and you will) you should ideally install them all fresh, i.e. re-download them or go back to original discs.
To make this easier, make a list of all your registration codes and passwords now.
Otherwise you will have to reboot from your clone to find them all anyway, so you might as well do it now.
HARDWARE
Forums seem to agree that not all ExpressCardSSDs will be recognised as bootable drives.
The FileMate48GB SSD seems to be the one that works for everyone.
Not all MacBooks will boot from the ExpressCard slot. Those with Model Identifier (“About This Mac”, “More Info”) ending 4,1 or 5,1. definitely will boot from the ExpressCard SSD. Others *might* but not everyone agrees on this.
THE INSTALL - OPTION 1
Insert your SSD into the ExpressCard Slot.
Use Disk Utility to reformat the SSD as a HFS+ Mac drive.
Insert your SnowLeopard install disk.
Install OSX to the SSD.
Select Custom Install to remove unneeded printer drivers, languages etc. as you don’t want to fill up the SSD.
Use System Pref to select the SSD as the startup drive and restart.
Run software update several times to bring your new OS up to date.
Use Disk Utility to partition your internal HDD to two volumes. Make one volume around 50GB for the system. The rest is your file storage.
Use CCC to clone your startup SSD drive to the 50GB HDD volume and set CCC to make periodic back-ups.
This way, if your SSD ever fails, you can still startup from the internal drive.
THE INSTALL - OPTION 2
If the install disk doesn’t allow you to install OSX to the SSD then do it in the reverse order:
Restart from the OSX Install CD.
Partition the internal HDD as above using Disk Utility on the install CD.
Install OSX on the HDD 50GB partition. Use Custom Install to avoid installing unnecessary languages and drivers.
Run software update several times.
Now download Carbon Copy Cloner and use that to clone the new OSX partition to your SSD.
Now use Startup Disk in the System Preferences to make the SSD your boot drive.
Its the same as above, but in a different order and should avoid any problems of the mac recognising the SSD as a bootable drive.
MOVE YOUR HOME FOLDER
You want your content stored on your internal HDD or your SSD will fill up quickly.
To move your Home (User) folder from the startup disk:
System Preferences
Accounts
Click the lock and enter your password to make changes
“Ctrl” and click on your account and select “Advanced Options”
Here you can nominate a folder to be your home folder.
This should be on your HDD.
Now iTunes, iPhoto and other apps will store their content here rather than on your startup disk.
KEEPING THE LIBRARY SMALL
It is easy to end up with a large Library folder which will become larger than the SSD can manage.
This is caused by Applications which have added content which will fill up that library.
Notable culprits are Apple Studio (i.e. Final Cut, Motion, DVD Studio etc.) and iMovie and Garage Band.
These will store large audio and video files in the Library (audio loops, video templates, graphical content for Motion).
In Apple Studio, you can choose the location for these files during installation. Choose to put them on the internal HDD.
For GarageBand you can do the same, but you need to use Terminal. Simple instructions here: http://www.macosxhints.com/article.php?story=20040117222032141
iDVD also uses up loads of space with its themes. Instructions for moving its theme library here:

By careful installation of apps from new, you can keep the library way below the 48GB of your SSD. The theme libraries above can easily swallow 20GB so moving them will make the difference between a successful install and a full start up disk.
FWIW themes and templates that are not audio or video based (such as MS Office templates or iWeb themes) take up hardly any room so don’t worry about trying to move them.
Now you need to rebuild your iPhoto, iTunes, email, network settings etc. which is a long post in itself.
These are all quite easy to do but need to be done carefully to avoid annoying issues (like losing the tags from your iTunes music).
You can Google these topics, or just post any specific questions and I’ll answer them as best I can.
good luck
