Building up a Jamis Dragon 29er from frameset, got a coupla questions

I've been out of mountain biking for awhile, but have the urge to get back into it. My plan is to go 29", steel frame, fully rigid. Something I've had on my mind for quite a while.

I've ordered an '09 Jamis Dragon 29er frame (Reynolds 853 steel), and I'm planning to build it up with a rigid Salsa 29er steel fork. I've got some pretty nice parts laying around, including some new old stock Shimano XT stuff from a few years ago that I plan to use for the drivetrain. I'm going to build what I hope will be a nice durable wheelset from new XT disc hubs, Mavic TN717 rims, 36 double butted spokes for both the front and rear. I'll go with Avid mechanical discs for the brakes.

I've never owned a bike with disc brakes, and never owned a 29er. So here's a question regarding the rotor size: 160mm or 185mm, and why one over the other? My planned use for the bike is XC trail riding. As for tires, I've used Stan's tubeless system on 26ers and loved it, so I plan on going that route with the 29er. I want a fairly large volume tire, say 29 x 2.2 to 2.4. I'm not sure what the Dragon 29er frame can handle as far as tire clearance, but I'm hoping it can handle most of the 29 x 2.4's out there(?). Tires I'm considering so far are Maxxis Ardent in 29 x 2.25, Panaracer Rampage in 29 x 2.35, and Continental Mountain King in both 29 x 2.4 and 29 x 2.2. Any tire recommendations, insight, etc. is much appreciated-
