When you say you're getting more backlinks... Do you mean that all of those backlinks are for the key "blahblah" link anchor text that you're trying to win in the SERPS?
There's no point getting dozens or hundreds of links with your site name, url or some other extraneous text in the link anchor. The whole point of backlinks are to have them for the text you are trying to rank for in the search terms.
Also, it can literally take 8, 12, 16 weeks for some links to pass their juice along. I've built hundreds of backlinks for a site, got worried because nothing was happening in the rankings and then all of a sudden, whoosh - top 5.
Just keep plugging along adding consistent numbers each day and eventually you'll see some results. Don't stop social bookmarking, pinging those social bookmark sites, your Angela techniques and so on. Grind away and eventually you'll hit paydirt.
