1. Can I use a Lincoln AC/DC Tombstone without the extra rectifier for Tig? I have DC+ and DC- up to 125.

yes you can.

2. What thickness of metal would the 125amp max be capable of?

1/8" with one single pass, thicker if you go multi pass welds.

Excellent videos. I have used them to learn as well as have recommended them to others who are just starting out.
