Looks like a good start, but I'm wondering if there is just a bit too much track. As I was reading through the responses to your layout someone mentioned using ground throws. I wholeheartedly agree that this is something you should consider. First, it will open up more space along your rights-of-way which will benefit your rolling stock (you might find you can run a longer car than you could with the switch machines in place), and secondly, since it is a primarily switching layout, ground throws offer the operator the realism of what an actual train crew does. Use a dental pick or similar tool to uncouple your Micro-Trains (or MT compatible) couplers and you have a pretty realistic, and enjoyable, operating session using 2 man crews (engineer and conductor/switchman). As for DCC, I think a layout like yours would definitely benefit. Just about all loco's from Atlas, Kato, and Life-Like are released in both DCC-ready and non-DCC versions. It may be a larger investment in the beginning, but the operational flexibility will more than pay for itself in the long run. Plus, if you start in DCC now, it won't hurt your wallet as much when you build that room-sized dream layout and decide to go DCC then, when you have a huge fleet of engines that need to be converted.
By the way, take a look at my layout, a modified Atlas trackplan:
