Flush Draw 101

[FishSticks]

PFR is 23/14/3 ~25 hands, has cbet his raises, seems normal. BTN seems very loose/bad, and is like 55/14/2 over that same sample. I'm obviously new here, and I don't have any reads of note.

Blinds - 4 Players - (LegoPoker HH Converter)

Hero (BB): $206.00
UTG: $295.00
MP: $237.00
BTN: $201.45

Preflop: Hero is dealt 4[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/heart.gif[/img] (4 Players)
<font color="red">UTG raises to $6.00</font>, MP folds, BTN calls $6.00, Hero calls $4.00

Flop: ($18) 8[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/heart.gif[/img] T[img]/images/graemlins/club.gif[/img] (3 Players)

Does anyone do anything different preflop?

What's the plan here?
