If you are going to be doing a CLEAN INSTALL you do it the SAME way as you would with a standard SATA drive. Just replace it, shouldn't require any BIOS changes, and install the OS. I would get a SATA II (I assume that is what your drive is now) as it could work a little better even though SATA III is backward compatible.
Now if you want to CLONE the original drive over to the SSD, specialized s/w is required.
Me, and I've done this, I used the original drive as a second data only drive. However, I had from day 1 partitioned that drive to a small OS partition and then 2 data partitions. This way I was able to clone the original OS partition to the SSD, then booted off of the SSD and HID the original OS partition (actually I changed the drive to another letter so I can access it if need be or even BOOT to it).
I"d check how much of your original drive was used and get a drive larger than that.
