Internal Link Strategy

Concentrating PR on two main pages of website

[milanmk]

I have the following internal link structure for my website.

Home <-> Page1 
    <-> Page2 
    <-> Page3 <-> SubPage3.1 
            <-> SubPage3.2 
            <-> SubPage3.3 
            <-> SubPage3.4 
            <-> SubPage3.5 
    <-> Page4 
    <-> Page5 
    <-> Page6 <-> SubPage6.1 
            <-> SubPage6.2 
            <-> SubPage6.3 
            <-> SubPage6.4 
            ... 
            <-> SubPage6.29 
            <-> SubPage6.30 
    <-> Page7 
    <-> Page8 
    <-> Page9 (it contains all external links) 
    ... 
    <-> Page29 
    <-> Page30 

Notations:
<-> Means two way linking i.e. PageA <-> PageB means PageA is linking to PageB and vice versa.
... Means truncated lines.

Page9 has all the outboud links and all those websites are linking back to the Homepage.

Questions:
1). Is this link structure correct?
2). Should I link SubPages3.X and SubPages6.X to my homepage or not?
3). Should my Homepage be link back to all the SubPages?

I want to concentrate PR on Homepage and Page6 as these two pages are getting good number of internal back links. Moreover, the theory of getting less hits on each pages instead of getting all the hits on Homepage is not feasible as this is comparatively a small website.

Any suggestions are most welcomed.

Page9 has all the outbound links and all those websites are linking back to the Homepage.

I find this extremely unnatural!

First, most pages of a site should link out to related pages in order to prove they provide related resources for their targeted keywords.

Second, it means all pages your site links to are involved in reciprocal linking with your site. It has all the appearance of linking schemes.

I don't claim these is wrong and your site will rank poorly. I just say it's unnatural and Google might penalize it eventually.

But I think your site can loose some opportunities it could get from targetted outbound linking and one-direction links.
