Should I call to see the TURN?

Hi all, I've just started playing poker and have clocked about about 800+ hands. And the book I've read so far is Lou Kreiger's 'Holdem Excellence'. Here's a hand I played, and I'm wondering if I should have called at the FLOP to see the TURN, and to notice I've a chance at a [img]/images/graemlins/club.gif[/img] flush draw.

SHOWDOWN
Bee37 wins.

Now on hindsight, I should have called at the flop, since it's only a small bet, and I might hit an Ace on the TURN to give me a two pair, or hit a 3 to give me a set. In addition, I am holding a backdoor flush at the FLOP. Looks like the pot odds are good in my favour.

So is my reasoning correct?
