For the wild rhino hide armor, I deconstructed the cost for +2 hide armor, figuring the charging special ability was a 1,000gp add-on. So we have 4,165gp for the base, then add the wild quantity, which is a +3 bonus, equalling +5 armor. +5 hide armor is 25,165, plus the charging special quality for 1,000gp = 26,165gp for the wild rhino hide armor.
As for Claw, sorry, my bad. I'm used to AU animal companions, which do increase in size. So... Claw's Str goes down by 8, his Dex goes up by 2, his Con goes down by 4 (and his hp), his natural armor goes down by 2, and his AC and attack go up by 1.
For the greater magic fang, Burrow is capable of casting it, he would just have to find a friendly wizard to cast permanency for him. (That is, if the DM would allow someone else to take the XP hit. Hmm... but then he would still have to pay for the spell. Whoops!)
Sorry for the point-buy and weapon size goofs.
