LP range in the 5NL micros - full ring cash games

In the last few thousand hands I've been getting crushed in late position, and I'm not sure if it's the way I'm playing post-flop, if it's variance, or it's my opening range. (Btw, I play full ring, 9 max, 5NL cash games at Full Tilt.) Here are my combined starts for CO & BTN....

• VPIP: 28
• PFR: 16
• 3Bet: 4.9
• 4Bet: 1.9
• Att to Steal: 31
• Fold Steal to Blind Reraise: 38

More or less, my range is roughly as follows in LP....

• Raise Limpers & 3bet: AA-TT, AKs-AJs, AKo, KQs
• Raise First In: same as above + 99-22, any Broadway, AXs/o, KXs, K9o, Q9s
• Call Raise w/ no other callers: 99-66, most Broadway, A9s-A8s, K9s, Q9s
• Call Raise with other callers: same as w/ no callers + KTo-JTo, A7s-A2s, any suited connectors, occasionally suited 1-gaps
• Open Limp: never
• also, LP first in raises are usually ~4bb+1 per limper.

Again, this is a little rough, but you get the idea. Any suggestions? Am I too loose? too tight? too agro stealing? Help! Thanks.
