Additions to current website

Hi, I have a current website called www.bondiclassifieds.com.au. We'd like to make some additions as per below... (1) when a user uploads an image I'd like a secondary function added so it also displays as a thumbnail next to the listing. 2) delete the quick search function and replace with a function which pulls the 10 most recent postings into that space 3) add a google maps function for users to add to their listing 4) perhaps add a rss feed on the homepage to pull the latest news on the site as well. BC is coded in php and css
