2nd. This is the best option. Also I recently (last weekend) did a 13 lb BIAB with a 9 gallon pot.
I didn't really have all the room that I wanted and i got 65% efficiency. What I would recommend doing is if you have a second pot, I would split your grain bill. Because IMHO if you get the wort from multiple pots and are able to have them touching more water, its similar to extract where you add them all together after the mash, and its not as much to lift once its soaked. So like 9 lbs in the 10 gallon pot, and 6 lbs in a 5 gallon pot. It is easier IMO to do the smaller one on the stove.
As for pulling out the bag, i will make a shameless plug for my friend's site www.brewgeeks.com
and say that they had a phenominal idea for the straining, they took a mixing tub cut a hole in the bottom and put a grill grate over the hole, so that they could place it and it would drip into the pot:
