Advice for for a cycle bike/problems with disk brakes?

A flatpack bike I recently got has a few problems.

Well firstly, it feels like I'm riding up a mountain on really low gears, compared to my last bike I seem to be doing twice the work.

I investigated, did some tweaking on the disk breaks, a little less rub, but still some.

Tried again, not a giant difference.

Does it seem I need to try to altar the distance of the pads from the disk? I peered into that general area, and there doesn't seem to be any gap at all between the disk and the pads. I haven't done this yet.

Oh and an added bonus...whenever I put too much pressure on the pedals, the gears randomly change and bugger up....a solution I think is to tighten up the chain?

Any advice?
Thanks
