New Joomla site set up help

This is a new joomla commercial business web site template with K2 (has several extensions installed) that will showcase products. It is not retail (no ecommerce needed yet), however there are features required. 1. I have a mega dropdown style menu system and it's confusing for me to set up the links having never worked with joomla before. So I need someone to set up the navigation and give me a quick overview as to why you chose to use the menu item types that you used so I will understand the system better. The product menu will be tiered from category -> sub-categories -> and then finally item page with images and descriptions and cost for each. I have no problem if you start it and I finish it assuming you show me how. 2. I have a flash module installed for my flash banner but the banner is not appearing. Need this fixed. 3. An "Add to favorites" for each item (not looking for "add page", I need by product similar to Add to Cart, except it's favorites that the registered user will be able to see as a list when he is logged in. Admin needs to be able to run reports such as most bookmarked, by whom, etc.. 4. Auto suggest for searches. (like google's system) I'm hoping some of the above are available extensions. But if not, you should have enough experience to complete this easily. Past joomla sites required in your portfolio. I reserve the right to ask for modifications until I'm satisfied. I may ask you how to go about adding product and images and some layout questions like how to hide the blog features on the product pages for example. Payment released after client approval.
