Deep woods hydraulic leak remedy on '99 Suburban 454

[NickBurn]

Hey folks: ('99 Suburban K2500 3/4 ton 4wd 7.4 liter)

I was 50 miles out in the north Maine woods with my family (young kids) when a seal blew in my hydraulic brake booster. Lost all the power steering fluid before I even noticed the noise from the angry pump over the music and dirt road roar. Because I figured I already fried my pump I decided that, instead of being stranded, I would risk putting in a little two stroke oil (all I had with me) to at least get us back to camp. Once at camp I took the boat on a 30 mile ride and found some tranny fluid from a generous guy (I was really out there - lucky to find anything remotely suitable as power steering fluid). That nursed me home, and now I am wondering if I replace the booster and pump, how do I make sure the rest of the system is flushed and not damaged by the 2-stroke oil? Also, can I find rebuild kits for that booster? NAPA doesn't have 'em. Last question: Once I replace the parts and flush the system (not necessarily in that order) does it bleed automatically? I mean can I simply fill the power steering pump carefully a few times until the whole system is up to level, without doing any air bleeding or anything? Thanks for any help.
