Should I keep up dealer maintenance?

Normally I would shy away from a vehicle with 200,000 miles on it, but the previous owners did everything at the Honda dealer and kept every record. I got a literal thick folder of stuff when I bought it. It was well taken care of, and all maintenance was done on time, no expense spared. The only reason they traded it was due to getting a brand-new Odyssey.

My question is, as someone who can't afford to go to the dealer for everything, am I okay doing most things on my own? I plan on taking it in for complex tasks like timing belt and stuff, but will I be missing out doing oil changes/brakes and similar maintenance at home on my own?

I know most shops inspect certain items (I've read in these maintenance records that the dealer checked stuff I'd never think to look at) when doing maintenance, and I don't want to miss anything simple that can be avoided. Thoughts?
