SSD Hard Drive Replacement Choices

So I technically can't have 2 drives inside my MacBook Pro...??? Thanks for any, and all, of your help.

Sorry, I should have visited you link before posting. I was not sure what you meant by optical drive, AWESOME. I never use the CD/DVD drive anyways. If I do need it, I can always plug an external drive. Thank you for your help! Any chance you would know if a novice can perform this task? Or should I take it somewhere?

Also make sure to take advantage of the Chipsets 6gbps capability by getting an SSD that's "6G" capable. Really Fast!!!

Yeah, the actual drive I am looking at is a : Corsair Force 3 120 GB SATA 3 SATA 6.0 Gb-s 2.5-Inch Solid State Drive CSSD-F120GB3-BK : It is definitely a 6GB/sec. To the best of all of your knowledge, is this a good drive choice?

Here's the guide for installing the optical bay adapter. I would put the drive in that. Crucial is a well respected company and that drive should be fine. Just look through the guide, spot the correct tools at the start of the guide and you should have no problems. Remember to format the new drive before installing a system. This way you will be able to boot from either drive, retain a 10.6.8 system so if you have Power PC programs, they will run and install Lion on the new drive. You will be able to run Disk Utilities on the non-booted drive to repair when needed. If you decide to accept this answer please wait until after 2 AM CST as I am maxed out on points for today and it won't count. Thanks and enjoy your new drive.
