During the bumper-to-bumper warranty period, I always take my vehicles to the dealer. That way, I know it's done correctly, and I have maintenance records showing that it was done, just in case a warranty repair on a serviced item rears its ugly head.
After the warranty period, I'm a little more loose on who does my maintenance. I do the simple stuff myself, but take it to my trusted Honda mechanic for the things like you've put in bold. I always keep the detailed receipts, take notes on what I've done myself, and keep it all in a folder.
