Also I just want to confirm that I am removing just the one head bolt cleaning out the hole and then putting it back in. Is this something I should do as a hot engine operation or should I do this as a cool engine operation?
I haven't done a lot of this kind of stuff before so I figure it's better to ask more questions then damage something further
Also would it be beneficial to drain any of the coolant before I perform this operation?

Cold. And just remove the one bolt.
Just be slow when running the tap, and really take your time getting it started. Then clean well.
That tap looks fine. You only need it to fix one hole. You could always run it down a metric nut the same size to make sure it's decent before going after the block. If you're anywhere near me (93117 zip code) you're welcome to borrow whatever you need.

It can't hurt to clean the threads well and retorque this head bolt, but I think it is unlikely to resolve your problem.
The long tap should make the work easier.
Work on the engine cold. Don't think draining coolant will help..
Good luck to you. and keep this updated please

Apologies for the long time between posts but I think that I have finally solved the problem. after running the tap down the head bolt that wasn't on right i was still losing coolant, but the engine was running better. I also found that one of the manifold to down pipe bolts wasn't on al the way as well and that mostly took care of the misfire that i was having but i was still losing coolant. i ended up giving in and buying some UV dye and found that it was leaking from the heater core return line after some online investigation i realized that i had never put the bolts into this pipe in the first place
but after about 2 hours of work i now have bolts in the pipe and so far there are no new leaks. i am honestly surprised that the coolant wasn't just dumping out of the pipe and that it was just slowly leaking out to the point that the overflow was empty every 7 to 14 days.
