If you're worried about losing lures to snags, make a $15 investment and spool your reel up with some PowerPro. The diameter of what you're using now should give you about 25 or 30 lb test...so if you happen to snag, you can usually rip the lure free. If it's REALLY stuck, you just wrap the line around something sturdy, like a stick, or the handle of a net, and pull steadily. The line will last a looong time, and when it looks like it's time to change, you can take it all off, and put it on the spool backwards...using the untouched stuff that's been buried at the bottom.
As for lures, well, the sky's the limit...but definitely get yourself a white spinnerbait...one hook to worry about, can be fished shallow or deep, and even skimmed over top of weeds without getting caught up TOO much.
As for where to fish...look for the "differences" in your spots. If the whole area is weedy, look for the log, or rock, or even just the hole in the weeds. Where the depth changes. Where the water goes from calm to choppy. Where water is flowing in, ie. from a creek.
