At the time when these SSD optimization tweaks were written, most users were maxed at 4GB RAM. If I only had 4GB RAM right now, then I would disable Superfetch. Reason being even though the usual frequently ran programs get fetched onto RAM, because the lack of RAM (yeah, I think 4GB is not enough), they will be replaced with any other data sooner or later. Even though reading from an SSD is really quick, this will just make more disk IO during boot. So I think it makes sense to disable it ONLY if you have 4GB or less RAM.
These days RAM is so cheap you can get 16GB kit for $40 to $60 on special deals such as after rebate. With 8GB RAM, I would keep the Superfetch enabled because the RAM is darn fast at everything.
I think the tweak instructions should be updated. Also, I never seen defrag schedule getting disabled automatically when I install Windows 7 on a SSD. I tried on intel X25-M(80GB), Samsung 460 (256GB), OCZ Agility2 (120GB). I had to manually disable defrag schedule on all of them.
