Views, hooks or handlers?

I currently have a very large set of Views that I am refactoring. These views work with a set Taxonomy and pull in the content that links to that Taxonomy. However the work that I am doing in the refactoring is going to result in the following necessities, when the Taxonomy gets added/updated by the user, and there is a new View catering to the content that uses it:

• Dynamically modifiable Taxonomy values
• New path
• New Global Text
• New Views Block that acts as a Tally counting the usage

Removal of the Views when the Taxonomy item is deleted, without affecting the others in its group.

So what do you think I should be looking at to accomplish this? 

Hooks or handlers? 

Or ditch Views altogether, and only use it to help get the correct SQL in the mockup phase?
