- is the bottom content ok? please scroll down all the way. --- **The content is good. It should help your homepage rank for a lot of long tail keywords, provided it's optimized for them. **
2) We used semantic keywords for 5-6 anchor interlinks to the same page to promote core products from the home page. Is this too much? - Anchor Texts to the same page won't help. If I were you, I would rather send 5-6 important links to the most important (different pages). Multiple links to the same page from your homepage won't help IMO.
3) We repeated footer path the same as the header fly window (same link, same word), is this over-optimized? If not, does it serve any SEO? -- I don't understand this part of your question.
