It's a bit tricky to follow the action, but generally speaking, committing with top pair is a good idea versus a very loose opponent. So once you've established that you want to get it all-in, it's a matter of trying to figure out how to best go about it. One way might be to simply push the flop, if you think he'll call with any pocket pair, any wheel draw and any ace. If he might lay down weaker hands than top pair to that kind of action, but is bluff-happy, then just calling and going for a check/raise on the turn is a good option.
The tricky question is whether or not to commit. With your description, there's no reason not to.
