Don't look at sequential speeds to compare SSDs; you are not buying these to store large files like movies and music; but to function as a system drive with many random access. For that purpose, you should look at random read/write IOps.
You will find that Intel controllers surpass any Indilinx based competition. Many OCZ SSDs are powered by an Indilinx controller. Since the Intels are only slightly more expensive per GB than the relatively slower Indilinx drivers, this would be your best bet; the 40GB X25-V or 80GB X25-M.
Regarding your other question (please try to keep it in one thread if possible) - Windows 7 installs pretty well to SSDs; not much you have to do. Set the SATA controller to AHCI in your BIOS before you install Windows 7; this is required to use NCQ and greatly speeds up the multiqueue performance of your SSD.
After installation, check with the benchmark utility AS SSD (google on it) to see if your partitions are properly aligned; it should say "1024K - OK" or something similar, and not "31.5K - BAD".
