You are doing well, Amanda! You got off the couch! I agree with SG that you seem to be doing too much quality. I would ignore SG's paces, though! You are aiming to run 10 minute miles so the suggested paces are, knowing SG, a mistake!
I would forget about distance iniitially and build a pattern across the week working on minutes run, plus the gym session:
e.g. Week 1: 4 runs, 20 mins, 25 mins, 35 mins, 45 mins, all at a a relatively comforatble pace;
Week 2: 25, 25, 35, 50
Week 3: 25, 30, 40, 50
That sort of prgressive consistency will work wonders! I would let the pace develop after 6 weeks or so, not least through increased confidence. If some of the runs are off road, or hilly, and you can cope, so much the better. The runs can be run in any order, e.g. longest run on Sunday, shortest Monday, Next longest Weds, etc etc.
