First I'd recommend reading library copies of Bernstein's "Four Pillars" and Bob Clyatt's "Work Less, Live More". Both recommend specific portfolios and Bob's book delves into withdrawal methods. A link to Bob's book is at the bottom of the website.
You can also read more about retirement planners & withdrawal methods at the FIRECalc page.
Your plan sounds fine. There are many different methods to withdrawing your portfolio during ER, and in subsequent posts you're gonna see all of them in excruciating detail. You can make it easy or you can make it awful complicated. If you stick with your approach then rebalancing once a year (how much & where depending on market performance) is probably sufficient.
Many of your questions have probably already been addressed in the board's other 100,000 posts. The "Search" button at the top of the page will let you look for keywords and help sort out the chaff.
