UAW works but in very general keywords. Try Syndicate Kahuna. Read this POST (
http://www.blackhatworld.com/blackhat-seo/blogging/41168-anyone-have-expereince-syndicatekahuna.html) where I talk about my experience with it.
In Platinum SEO Plugin Options: I suggest this:
Mark 301 redirects. Fill Title, Description and Keywords if thy are empty. Rewrite Titles: ON. The rest until Paged Format leave as default. META keywords: OFF and the rest ON.
Go to Settings and Permalinks and change it to Custom Structure and set it to
If you mark 301 then all the links with the structure yourdomain. com/?p=123 will be directed to yourdomain. com/title_of_the_post instead of getting an error.
Mark
Noindex because when Google visit your blog will see that you have the same content in home, categories, archive.... and will mark it as duplicated content, so less ponits.
Mark
Nofollow: you shoul read a bit of SEO. Briefly: with each external link you lose juice link (pagerank). If you control blog farming then you can change this.
Autogenerating Descriptions save your time.
Additional headers is very useful if you have a script that tells you to put something in your header. Imaging you want to set a text link script as Kontera. You have to insert a script in your template. You can insert in on footer but the it will be shown everywhere and you don't want it in home and pages, only in posts. Then instead of installing it in the footer.php of the template, you can insert it in Additional Post Headers.
Now you have a new form when creating/editing posts and pages with the name: Platinum SEO Pack.
Title: you can set here another title to your post that will be shown in the name of the window when your see that post. You will have your post more heyword related.
Description: if you marked Autogenerating Descriptions you can leave it blank. If you fill it, it will be shown the description you set up.
Keywords: I leave it blank because I have Simple Tags plugin and keywords are duplicated. So the best is you test it (Preview you post code in your browser).
Next, set "index, nofollow" (read the explanation I wrote before to custom it)
Large explanation.... I don't know much of SEO so perhaps this settings aren't the best. You can go to the author plugin to read more about it. Anyway, if you have a question you can contact me by AIM.

Edit: Adsense bans the site that isn't following its TOS so if only your first subdomain is found in fault only the first will be banned.
You can make subdomains the only problem with same IP is if you link them eachother.
