FTP is quite regged up - maybe the $2.25 and below are OK, but above that its the fish become somewhat more scarce... then again, it sucks to have low traffic and wait forever to find enough tables to play. FTP is fine IMO if you're willing to table select.
If you want to learn proper SNG/MTT, just watch the videos on this site. Watch how they play these things, understand their reasons for playing the way they do, and copy it
However, if you have a problem with variance and get upset easily, maybe SNG's are not for you. You can be playing virtually with no mistakes and still have 10-20 BI downswings EASILY. The push/fold nature of the game just introduces a lot of "luck", so you need to play quite a lot to overcome variance.
If you want minimum risk, I suggest you try learning fullring BSS cash game poker. It tends to be far less swingy, and the videos on this site (mainly Hasenbratten) are really great.
Hope this helps
