Having my gears installed finally next week in my 02 Tacoma. I've read the standard break in procedure but what should I do about the front diff? It's ADD so it does spin some but without it locked in only the spider gears spin mainly. Should I lock the front axle in so it's spinning or just leave it? Also does anybody have any gear oil recommendations for break in?
 
My instructions to my clients is to drive like you have sense for the first few days. Avoid things like towing, hard wheeling, long trips, etc. In your case I wouldn't do anything funky with regards to the front diff. If you wanted to you could put it on stands and drive it in 4wd for a bit.
I use 80/90 and 85/140 non synthetic in every diff I build. No need for synthetic during break in (or ever in a wheeling rig IMO).
