You need to be selective when deciding whether to bet whiffed overcards into multiple opponents. Following up on the turn is often a good idea when you're down to one opponent, but you should usually then take the free showdown if you have position -- it's part of the point of betting the turn (seeing the showdown without having to put any more money into the pot).

It's not enough to have the best hand on the river... you have to be a favourite when called. Ask yourself:

1) what worse hands will call?
2) what better hands will fold?

Folding out hands that you would have beaten anyway is pointless. If they've gotten that far, they probably aren't folding any piece of the board. Not too many opponents will regularly call down with A high (especially kicker < T). Usually a bad recipe for a river bet UI.
