Below is an excellent link to a fact sheet on betta tank mates, and compatibility with other fish.
With those tank mates, do only one other species. That is, get either otos, corydoras, or african dwarf frogs. Corydoras do best in groups of 4-6, so a small school plus your betta would be perfect. Or a group of three otos, as they to go best in groups. Again, African dwarf frogs (ADFs) do best with buddies, so getting 2 or 3 would not overstock the tank. Always better to understock, as opposed to overstock, and putting 1-2 ADFs, 2 ottos, 3 corydoras, and 1 betta would definitely be overstocking. I would highly suggest against adding a molly to the tank, especially one as small as a ten gallon.
I hope this helps! Oh, that forum that the fact sheet is on, I highly recommend it :)
And Jordan, African Dwarf Frogs are completely different from African CLAWED frogs. ACFs eat fish and grow huge, ADFs stay quite small, and pose absolutely no harm to a betta. And otos stay quite small as well, you must be confusing Otocinclus with Plecostomus.
