Some bugs and features required

Bugs:
1. URL alias doesn't work under 0.7.7.
2. Search result lists disabled products if "search description" checked.

Features wanted:
1. Price range search.
2. Want to have  "best sell" or "top hits", "recommanded products", "special offer", "featured products"  on home page. Currently there is only "lastest products".
3. "Write Review", "Reviews", " Inquiry", "Tell a Friend" tabs on the bottom of product page.

Anyone can help?
