This year, this tree of mine has some branches on it with green leaves (instead of red leaves). Other than the fact this is unsightly, do I need to cut off these branches so it won't affect the tree as a whole and cause all the leaves to turn green? Or, is there something causing these leaves to be green - something I can do as far as fertilizing or minerals or something to keep the tree producing red leaves?
Any chance it's environmental (i.e. a shade or artificial light effect) and a genetic reversion? I haven't seen this in palmatum, but I have in other deciduous Cvs?
I'm not sure what "tidy up" means here, but the best way to remove tree branches is to make a proper cut just outside the branch collar and leave it at that. For more info, see link in sig below.

Since virtually all cultivars of Japanese maples are grafted on to a more stable rootstock and the dwarf laceleaf cultivars tend to have high grafts, the green reversions could very well be orginating from the graft union. Remove them cleanly at the branch collar.
