There are many, many sites on the internet which describe, explain, outline, summarise, and otherwise go on about the BBT.

ToSeek has already given one of the best (IMHO), though I'd've pointed to Ned Wright's tutorial rather than the FAQ.

Another good one is the Cambridge Cosmology site. The WMAP cosmology section gives a shorter, simpler summary. If you want to know all about the CMBR, and are comfortable with first year university level math and physics, Wayne Hu's site is excellent (it also covers other parts of cosmology, but not so deeply).

I should also mention the 'size' and 'recession speed' non-issue (in most models which fit the data well, all objects with a z above a certain value are 'receeding' from us at speeds in excess of c). There are several excellent materials on this, from Lineweaver and Davis (I seem to have misplaced those bookmarks just now).

If you have any questions that these resources don't answer for you uniqueuponhim, please ask here!
