Top pair decent kicker on a monotone flop

I'm not sure if I'm playing these types of hands correctly. Table seemed mostly passive and straightforward.
I'm pretty sure the preflop call is pretty loose and not recommended, but I felt like I had a good handle on the table at the time. I'm mostly concerned about the flop, and if anyone recommends just letting it go there. Please reply with any comments though, I welcome them all.
