One thing that comes to mind on the compressor is if it's going to be in your work area your better off with a belt driven than a direct drive...... As the noise will be much less...... Look at Lowes or Home Depot you can get a larger one for about the same price

As far as the floor jack the biggest jack I've ever had was 1 1/2 ton and it's done everything I ever had to do so 2/12 or 3 ton should be fine
