25 NL 56s flopping trips

[Kazimyrch]

I've just started playing cash. Before I played a lot of STT's, mostly $20's and $10's, but I became kind of bored.
This hand I got 56s. I'm at the table for some 35 hands, being weak-tight. Villain seems solid.

As a newcomer I wonder how my line is. Preflop calling is bad? Should I raise the flop? Don't avoid being harsh in your comments. I like to learn as fast as possible. Thx.
