Some ticking is ok. If you have the oil pan still off, reach up there and see if there is any play in the connecting rods/bearing caps of the pistons at the crankshaft. Shouldn't be any noticeable play. I hope your old oil looked clean when you were draining it - very black and/or metal particles is a bad thing. You should check your oil pressure with a mechanical gage >10 at idle with warm oil, 40 psi or so cold and while running at RPM. Even though it may not be low enough to get the low oil light, it still may be too low. You could have a valve problem, but if your compression check on each cylinder is good, you could eliminate that.

Can't think of too much at the moment.
