1) You actually have 5 outs, you could get trips if your bottom pair gets a third card, so 10:1 is enough.

2) Your second question is tougher. I never played .02/.04, and I don't multi-table due to computer limiations. However, my general rule is that I give players credit unless I have seen them do something which indicates that they are likely to bluff raise. If you have no read, I would fold if the pot odds aren't there, and then watch that player in later hands to find out how they play
