Playing big aces in early position

[McDirk]

Does anyone have any tips on playing these? I run into this problem often, especially at the 25 and 50NL games I frequent where I won't have any information on my opponents. I'll have AJ/AQ or even AK in early position, raise (or often limp with AJ) and catch an ace or TPTK. Then I'll make a continuation bet on the flop and get a caller in LP. What's the best way to proceed from here when you've got a good hand that can extract chips from those people who think any paired ace is a good ace, but also avoids losing a big portion of your stack to someone playing Ax who caught two pair on the flop or happened to have a bigger ace than you? Thanks.
