Awesome post dude, please do keep us updated as to how things improve over the following months, even if it is less the money.
Your attitude on alot of the issues you brushed on, were bang on IMO. The one thing I wanted to bring to light is that this is just what you've made in the first month.. not neccessarily what you'll have made off of these sites in total. All of those sites will be in an archive or two and those sites can still make you money.
Last but not least, the only other advice I can offer you is to make sure you have a link hub somewhere (preferably at the root of all the domain(s) you submit under) so that you can have a little page with links to all your free sites and place a link on all your free sites to that hub page. Helps both SE's and surfers who might not like what you're giving em on that site.
Cheers!
