the bolas launcher doesnt seem very do-able. the quarterstaff idea has already been done, so you could strait up buy that (50gp). utility belt u could enchant for holding, but that would be costly. 2, 3, and 6 seemed right on the money. for your boots, i could only think of one idea. have a wizard cast a slight "levitate" (only 1/2 an inch or so) and cast "permanency". This would also help with rough terrain. One final note. Batman is probably closer to assassin or fighter. Ninja too squishy and stealthy like the common rogue
