Hi,
Lets focus on one area, the starting issue. Once that is figured out, chances are it will fix the other issue.
First have you checked for diagnostic trouble codes? IF you haven't you really should scan the computer. I realize most people don't own a scanner, but often times, a parts store will do it for free.
Next, we need to see if there is power to the starter. The large wire at the starter gets 12v all the time, and is most likely not the problem since you can jump it there. The smaller wire on the starter (S - Terminal) should also get 12v but only when the key is in the start position. You will need a helper to check that.

Next, confirm the following fuses are good in the under hood fuse / relay box. See pics 1 and 2. I also need you to check the starter relay.

In addition to checking the fuse, make sure there is power available in to it and back out.
