Definately recommend ts fs 1's first. I got those alsmost immediately. The real trick to riding switch away from a trick is to case the first few times so that you can concentrate on keeping the board straigth, and leaning back with both legs bent.
big question though: now that you're switch, what do you do? I recommend either a surface 180 or hs half cab. both are relatively simple...just ride for a while to get used to switch though. hop 180's are fun too though, and not that hard. Just don't pull the handle too close, or you won't have anything to hold you up.
good luck with that.
