Is there an search marketing / keyword tool in existence that can solve my need?

[PTC4SEO]

I'm looking for a tool that can do the following:
Organize a keyword universe and its data/metrics:
-track keyword data over time (search volumes/trends, relative competition metrics, rankings,
etc)
-Sort keywords into buckets/silos/ad groups
-allow you to assign individual keywords to multiple silos/groups and show the relationships between groups based on keyword relationships.
-incorporate a site map 
-tie keyword targets to static pages, informational content (SEO) & landing pages (PPC)
-help with KW and/or competitive research (optional)
-tie into web analytics / marketing on-demand software (optional)

I know that this is a lot of functionality, but for enterprise search marketing, this could be a game changer for my strategy (if it exists currently) or for the industry (if it doesn't exist).

Please share you solution suggestions here...

Thanks Stephen. I have done quite a bit of searching and it's the site map portion (creating relationships between pages and KWs) that I can't seem to find in a tool that is meant to tame a KW universe. I've been thinking that a custom tool might be needed, but I don't have much knowledge in the software engineering space. Funny, because I work for a multi-national billion dollar software solutions enterprise...
