I know this babowa has had their question answered, but I thought this could be helpful to others.
If you have just one hard drive in your computer (12 steps - total time: about an hour):
1.  Go to Disk Utilities and select your hard drive.
2.  Click the partition tab, click and drag the current partition smaller by about 20 GB (if you have it to spare)
3.  Click the + at the bottom (it should fill the blank space remaining), select the new partition, name it "New_Snow", set the format of the new partition to Mac OS Extended, and then click "apply".
4.  Insert your Snow Leopard disc, and reboot holding down the C key (this should boot to the installer).
5.  In the installer, select the "New_Snow" partition that you created (NOT THE BIG ONE WITH ALL YOUR STUFF ON IT), click the customize button when you see it and deselect everything - this installs just the base operating system and will be the quickest.
6.  When the computer reboots, hold down the "Option" key, and select the "New_Snow" partition to boot to.
7.  Once in the Snow Leopard OS (can check by seeing if Launch Pad is in the dock), insert the Final Cut Express disc, and install it and whatever else you want to your "New_Snow" Partition.
8.  Open the apps, register them, and enter in the CD key.
9.  Use the software updater (found in the apple menu) and choose to update anything associated with Pro Apps and Final Cut Express.
10. Reboot.  Hold down the Option key again, and select the Lion partition this time.
11.  After you have booted into Lion, go to Applications>Utilities>Migration Assistant, and select the following settings:
  a.  From another Mac, PC, Time Machine Backup...
  b.  From a TimeMachine backup or another disk.
  c.  Make sure your "New_Snow" disk is selected.
  d.  Deselect everything but Applications, and continue with install.
12.  If you want, keep the other partition as a backup (it has FCE on it already and everything) or use DiskUtility to remove the 2nd partition, and resize your Lion partition back to full size.
Here is the short version of this method for people who know how to partition hard drives and do reboots, etc:
1.  Create a new partition on your hard drive
2.  Install just the base SL OS to the new partition
3.  Boot into your new SL installation, install FCE, open it and register it, and run the FCE-associated updates
4.  Boot back into Lion, and use the Migration Assistant to transfer only Applications from the SL partition to the Lion partition.
Total time spent using this method is about 1 hr + (including FCE updates).
  5 mins to set up the new partition
  20-25 mins for the base OS install
  10-15 mins for the FCE install
  10 mins for updates
  5 minutes to transfer apps from the SL partition
Notes:
I bet the "install Rosetta Stone" method would have worked too, but I didn't try it.  I already had a second partition set up on my computer with Snow Leopard; so, all I had to do was boot to it, do the FCE install, then transfer it to my Lion install with the migration assistant. 
Hope that helps someone else who doesn't want Final Cut Pro X or doesn't/can't afford the upgrade for $400.  I figure even if it took you 4 hours to do, you're still likely saving $100 per hour.
FCP X download - 3 hrs
Installation - 15 minutes
Immediate learning curve issues, etc. - a few more hours
Updates - 30 mins
total alternative cost about 8 hrs and $400.
Good luck to all.
