I'm surprised no one has mentioned DDI as an alternative for buying books. As a somewhat new DM myself, Wizard's online D&D membership has been a great tool for me. While it doesn't really teach you -how- to play or run things (for that, the books have no substitute) you can avoid, for the most part, buying stacks of books just to get access to new races/classes/feats etc.
The character builder is updated somewhat regularly and, again while it doesn't teach you how to make characters, it does so a majority of the work for you. I find a monthly payment a much more attractive alternative to buying book after book. Plus you get all the other little tools and access to the online articles. The tools may leave something to be desired, but they can be helpful if you want to use them.
All this being said, if I had my druthers, an infinite about of storage space and disposable income, I'd rely solely on the books. There's something gained from flipping through books as opposed to click through internet tabs.

I'd like to second this. If you're afraid of spending too much too soon for only bits and pieces of the whole, DDI with its compendium is a good alternative. Plus it comes with the character creator, which I have found to be invaluable to my campaign (especially with my brothers and their half knowledge of 3.0, assuming things didn't change. Protip: things changed a lot.)
I also love just making characters for some reason; seeing all the different class powers and whatnot is enjoyable to me, and having all the sourcebook powers there online is a great way to save me time and money.
One problem with this could be information overload, though. The way it seems to be going, you'd really have to do your homework to keep up with your kids .
