How can I rank internal pages?

Hello,

I have a website about consoles, on the homepage are a few thoughts about what consoles are and a short history. The main attraction are the pages about Xbox 360, PlayStation 3, Nintendo Wii, PSP Vita.

So, I want to rank my homepage and my internal pages about the consoles ranking for "xbox360", "play station 3" each one on a separate page of course.

Basically I want to rank brands. My main questions are:

1. How much link builing should I do for my homepage considering that I'm not really interested in ranking it as much as the internal pages? In percentage how it would look like? Random (stupid) example: 60% links to homepage, 10% to each internal page?
2. I guess I must do links for internal pages otherwise they won't rank good, only linking to homepage.
3. Considering the penguin update, my main keyword should be around what % of the overall anchors to each internal page?

Any help is very welcomed! Cheers.

Any help? I'm willing to reward usefull infos!

Be careful with brand terms. Google staff tend to manually adjust SERPs for branding terms and it sucks.
To rank internal pages, just keep building links pointed to those pages, read about siloing/PR sculpting and do good onpage SEO.

Yes - be careful not to over do your anchor text for your internal pages. It's very tempting to think "oh, it's only like 10% of my total links, I can't really be bothered to split the links to the internal page 30% anchor, 30% longer versions of anchors, 40% brand or "click here"".... so treat them like a scaled-down version of your homepage, and be very careful not to overdo it, just as you would be with the homepage (and that goes for internal linking to).

Well, I would suggest that you build links for each individual page separately. Each page should have around 10-15% main keyword and the rest 85-90% of links should be a mix ot raw links, long tail keywords, dummy keywords like click here and read more. Do the same for your homepage also. Use diverse sources for the links: web 2.0, social bookmarks, forum profiles for the raw links, video links, web dirs for raw links again. You may also throw wikis and blog comments in the mix, but not too much. Use them to diversify your backlink profile further. The more sources for your links, the better
