Request for information/pre-built site template

I am a newbie to Drupal. I have much experience with Wordpress but I am pretty sure that it is not robust enough for what I want to build.
I am interested in building a site where
-users can create a profile,
-upload photos of items,
-these items can be categorized by a checklist/category and become searchable,
-the user can then share their uploaded images/text blurb via Facebook Connect to their community.
-Multiple users need to be able to access at one time.
-Ideally the user will be able to just login to my main site via FB connect-however they will need it to connect to a profile on my site so they can upload/modify,delete items as needed from their profile.
-I would also like the site to be searchable by category so when a user uploads something new they can search by that category, or search by who they are friends with in their Facebook community.

I will admit that I am much more interested in finding a solution or template that is already setup for this where I am not recreating from scratch. I would imagine there have been many sites that have been created such as this-any leads on those would be great. I can easily modify from there to make it into what I want as I am above average at coding. Again I just rather not recreate the wheel here.

-Are there drupal templates/out of the box setups people have built that are available to plug and play (with a bit with modification of course)? I'm not being lazy in learning but I just have to think that this has been created a million times for different reasons.

Thanks so much in advance~
