I won't comment on your ability to run your shop from one breaker off that subpanel...since I'm from the school of over-kill when it comes to electrical. I will, however, advise you to carefully think through what will typically be on at the same time. Do the math...figure out the actual current draw from your list of what'll be running...and go from there.
If possible, make the outlets on the walls come from different breakers, to allow you to power more than one breaker's worth from them.
I also add a word of advise on you plans "for the time being". Running an 'extension cord' for 130' to power tools is going to be HARD on your tools...even if you do what I did...run that 100'+ extension cord as 12/2 Romex. It's going to shorten the life of anything you run for any length of time. There's no getting around that...the drop across that much wire WILL adversly affect your tools! So keep that in mind as you plan how long the "for the time being" stage will last...and use tools accordingly.
Good luck...and keep planning and asking questions!
