Website Changes

I have an existing website that I need help with. Most of the work is already done. I am looking for help with the following... 1.) User access - User will log in using a login and password and will stay logged in until they log out. 2.) Search Details - I'm unhappy with the how the results page looks when a search is performed. I'm looking for cleaner results. 3.) Directions - I have links on the site that will provide directions to a location in question. I want the link to got to any provider (mapquest etc.) that will automatically populate the address info from the website to mapquest for example. 4.) Upload pictures - I want to give users the ability to upload pictures. The HTML page is already there, but I'm having difficulty making this happen. Thanks, Dave
