Problems with PP's and overcards

[StuR]

This post has 3 hands in it, sorry if this is unpopular but they all have the same problem - I didnt have any specific reads on the main players involved in each hand, but if player read would help could you suggest the correct play against that type (understand?)

1) Party Poker 0.50/1 Hold'em (9 handed) converter (http://www.selachian.com/tools/bisonconverter/hhconverter.cgi)

Preflop: Hero is CO with J/images/graemlins/diamond.gif, J/images/graemlins/club.gif. Hero posts a blind of $0.50.
UTG calls, UTG+1 folds, MP1 folds, MP2 calls, MP3 calls, <font color="CC3333">Hero (poster) raises</font>, Button folds, SB calls, BB calls, UTG calls, MP2 calls, MP3 calls.

Flop: (12 SB) 5/images/graemlins/heart.gif, T/images/graemlins/diamond.gif, K/images/graemlins/diamond.gif <font color="blue">(6 players)</font>
SB checks, BB checks, UTG checks, MP2 checks, MP3 checks, <font color="CC3333">Hero bets</font>, SB calls, BB folds, UTG calls, MP2 folds, MP3 folds.

Turn: (7.50 BB) T/images/graemlins/club.gif <font color="blue">(3 players)</font>
SB checks, UTG checks, <font color="CC3333">Hero bets</font>, SB calls, UTG calls.

River: (10.50 BB) 9/images/graemlins/club.gif <font color="blue">(3 players)</font>
SB checks, UTG checks, Hero checks.

Should I bet the river for value? I was worried about a weak king and bet the turn to get the free showdown. Is this too passive?

Final Pot: 10.50 BB

I was stuck between dropping on the flop and calling down. I chose the later and think this is incorrect. Views?

So many overcards, so I dropped this. Once again, Is this too weak ?

Sorry for the lack of player reads and length of the post.

Any comments appreciated.

Hand one I think is fine. When you're called on a river bet I don't see you winning much of the time.

Hand two I check-fold the turn.

Hand three I play the same.
