Too advanced thinking for 25NL?

A little background: I have experience in higher games than this and I'm usually a tournament player. Though I get by on ring games if I give them a chance... Here's the hand: First one at the table (so no reads whatsoever)

PokerStars No-Limit Hold'em, $0.25 BB (9 handed) converter

Preflop: Hero is BB with J[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/club.gif[/img].

River: ($57.55) K[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players, 1 all-in)</font>

Final Pot: $57.55

For some reason I thought this was a bluff push. Generally a player at these limits will raise a flush draw on a flop like that, right? Am I giving him too much credit by assuming he would raise this flop with a flush draw? Calling this all-in is assuming he DOESN'T have the flush and is trying to bluff the pot....

Thoughts? Comments? Is it WAY past my bedtime or what??
