The mace is pretty good. Might be worth a million or two, but I'm not exactly sure. Searching the AH for similar weapons always works... but you have to under-cut the price if you want to sell fast.
The amulet is harder to estimate. It has almost perfect stats for an arcane resist monk, but the crit chance is very low, and it's a very important stat for monks. It should be worth a few 100k for a monk that is gearing up, but you could try to sell it higher first.
