NUTS & BOLTS: BLOG HELP NEEDED

I've spent two weeks or so out here in the blogosphere and I'm slowly settling in. But there are questions I cannot solve and finding live customer service out here is impossible. I'm hoping some of you blogmoms will find it in your hearts to help out this newbie:

1. My feedburner reads are inaccurate. The feed is active and viable but the stats are clearly wrong. How do I remedy this?

2. Which social websites are best to increase traffic for this category of blog? Del.icio.us? StumbleUpon? Magnolia? Do they really work? Are there any caveats to joining these communities?

3. Advertising. I'm using Adsense and will inquire to BlogHer when I'm up for a month. Are there other money-making opportunities I should explore?

Thanks a lot.
