$25 NL stars - My set comes on the turn and I.. drop the ball?

[jakrpanda]

I feel like I played this hand horribly on the turn. I had just sat for a few hands and had no reads on the villain.

Poker Stars, $0.10/$0.25 NL Hold'em Cash Game, 4 Players

UTG: $9.05
BTN: $21.70
SB: $22.55
Hero (BB): $23.15

Pre-Flop: 8 8 dealt to Hero (BB)
UTG folds, <font color="red">BTN raises to $0.75</font>, SB folds, Hero calls $0.50

Flop: ($1.60) 7 K 6[img]/images/graemlins/spade.gif[/img] (2 Players)
Hero checks, <font color="red">BTN bets $1.25</font>, Hero calls $1.25

Turn: ($4.10) 8[img]/images/graemlins/spade.gif[/img] (2 Players)
Hero checks, BTN checks

River: ($4.10) T (2 Players)
<font color="red">Hero bets $3</font>, <font color="red">BTN raises to $8.25</font>, <font color="red">Hero ..</font>



Ok a few things:

1. Should I have re-raised his bet Pre-flop?
2. Should I have called his bet on the flop?
3. Should I have re-raised his flop bet 3x?
4. When my set came on the turn should I have bet, even with a potential straight out there?
5. River fold?

All kinds of questions here for me. I want to play this situation better.
