Blogfarm + SERPs

Quick questions to all ya experts:

I have 2 domains (PR4, PR3) on two different c class ips. I am going to try and create autoblogs out of them so the content is pulled from various rss feeds and the sites remain fresh and updated. The purpose of these sites is to boost the SERPs for my money sites, therefore I intend to backlink my money sites from these autoblogs with the high PR.

Is this a good idea? Will the SERPs increase? Will my money site PR increase?

PS: the backlinks to the PR4 and PR3 site have nothing to do with the content of my money site, how important is this?

Thanks

The anchor of backlinks is the most important fact for keywords with high search-volume.

So you should first keep the content from the autoblogs, related to your money site, and use good anchor in your links.

Sure that your money site will increase in SERPS, but keep in mind, that only about 3 backlinks from a site is good. It would not be wise, to link back to your money site, from every post you make on your autoblogs.
