Too many links to the homepage is not so natural when you look at it yet most sites will have at least 90% of all their incoming links to the home page

That's an interesting observation. I haven't been looking for that specifically, but I have been building links to a limited number of information pages (three, as of now) that are a few clicks away from the home page. I do this to better flow page rank to other internal pages - which they seem to do pretty well.

So if I am trying to rank product page abc.html I will link to it from the home page as well as from those three internal information pages that I am trying to get inbound links to.

I might only throw one or two links at most at the product page abc.html itself.

Again, it is a relatively low competition / low volume keyword, so I don't know how effective that is with high competition / high volume keywords.
