Check for leaks in your fuel lines. If that's all good then you probably had a short from hell. Would need a new starter and repair or replace your harness.
Pfft, I started when I was 5, and I did it perfect the first time and every time. Noob.....Ok seriously just practice. Try letting the clutch go without touching the gas and see if you can get the car rolling so you can get the feel for when your clutch engages. Other then that it will just take...
The only way to tell would be remove the head and check with a straight edge. The machine shop will tell you if they can straighten it or not. Since it's aluminium head/iron block, the block should be fine.
There was a set of old seats sitting outside in the rain that I asked if I could take off there hands, since it was obviouse they werent going to sell them. They where s13, nothing special. Wanted to charge me $100. I laughed and have never been back.
