You should be ok with everything you have listed with the compressor you own for shorter cuts. I will say the 1/2 and 5/8's cuts are not going to happen, not look pretty at least and be hell on consumables.

The TD is a good machine, it is made in China but don't let that scare you. I think for hand cutting with the dual voltage ability it's a bargain, it does have a 4 year warranty, consumables are plentiful and decent price. Hypertherm makes some great little units also but have personally never used them, might check those out also but are going to be a little more expensive.
