Looking to try 6max online games need advice

Hey, thanks in advance to anyone who might respond to this post. I normally play 10 handed low limit games with the general strategy outlined in small stakes holdem by
Skalansky, Miller and Malmouth. I was thinking that I would really like to improve my short handed game so I wanted to play on the six max tables on full tilt for a while, and I was looking for some insight on good ways to adjust to the short handed games. First, I know I should open up my starting requirments somewhat but I do not know to what degree. I know I still want to avoid cold calling with marginal hands and do not want to call with weak holdings up front when I am likely to get raised behind, but do hands like KJo become +EV in second position? I normally have a VP$IP of around 22 percent playing 10 handed what is a good goal to shoot for in 6 max? Also, I figure AXo becomes playable in some situations but I feel that last time I tried short handed, I raised with these hands to much but it seems that these hands should show +EV in certain situations. I think I have a reasonable idea of how to play post since one often gets into short handed situations in 10 handed games but any advice on this topic would also greatly be appreciated. Also, is there any good literature on this topic? Any other advice on short handed play or good sites to find weak 6 max tables would help me a great deal. Sorry about the lengthy and disjointed post I just sort of spewed out some question I had. Thanks again for any advice you want to spare for a short handed novice.
