Power Steering Leak

I have a pwr steering leak which appears to be coming from where the hoses go into the steering box.

96 F150 XLT, 5L, 4Wd

My questions -
Are O-rings used where those flare nuts go into the steering box?
If so, is O ring special material?
Are those nuts hard to get off?
Any special tools required?
Can I use regular transmission fluid to refill or is there some special fluid to keep from eating the seal again?
oh and is there some special procedure to bleed after a fluid change/refill?

Thanks for any help,
