My Silo Design & Questions

I am designing my own custom Wordpress Silo utilizing unique Blog Titles and Blog Descriptions on every page and so far it looks like this:

Tier 1:HOME/INDEX PAGE= Shows main Blog Title/Desc + outbound links to my SILOS

Tier2: SILO PAGEs(Main Category)..Each Blog Title is the Category Name, and Blog Title is now the Category Description (Wordpress lets you set a cat_desc when you create a cat.)

SILO page will link back to homepage+link out to each tier 3 Article Page if its within the silo only.

Tier 3: 5-10 Article/Post Pages (children of SILO). Each Blog Title is now the Category NAME (in tier 3)...Each Blog Description is now identical to the Post Title. This was best I could come up with, without setting it manually for each website/post page.

I figure changing the blog title/description is better than having the same one like most web sites do, creating more dynamic H1 and H2 headers..

Do you think homepage will actually lose link juice because the tier 2+3 pages don't mention the main page keyword in their blog titles?

In last article of SILO, in addition to linking back to silo, should I link back to A) homepage, B) first article C) none..Just create a dead-end as shown in Yukons diagram?
