Hello everybody

I have problem maybe you can give me some advices. I have site that has 200 pages.
The index 5/10 PR.in index page i put 20 internal links. 20 pages 4/10 others 3/10

my question.
if i put all 200 pages in my index page (like my site map). is it will hurt my pr or got google penalty because hard internal cross linking?

and is there best another ways to get all my sub index 4/10 or maybe 5/10?
