As for displays, a monthly reprofiling for CRT is fine; this is the same setting the the high-end Sony monitors reminding you to re-profile. LCD? Less frequent, something like 3 months as the LCD itself don't really change, only the backlight (which gets dimmer as you use it)
Your idea is frankly good enough, unless you intend to do professional (ie earn lots of $$$ to print high end) printing. I'm having the Eye-One display myself. In future, if you choose to add the print module, you can "upgrade" and may even get a discount for the effort.
