Earlier today I was exploring a store named Non-Standard on one of the Japanese sims. I really like this store, because not only do they have awesome freebies, but most things are $20 or less (with the exception of skins which are very reasonable at $600). So here is a picture of all the freebies:

Skins, outfits, toys; located both upstairs and downstairs. There are also some great Chirstmas goodies here for $5-10.
As I walked out of non-standard I'd noticed a sign for a TVStation Sim. Well, I've never seen an sl tv station and decided to check it out:
Find the elevator and take it to the exhibition level. You'll notice the space suit is on sale for $5 and there is a complete free female avatar (skin, hair, shape, suit, bag)
After I visited the exhibition I took a stroll through the adjacent sim Machinima and checked out all the different sets available. If you haven't taken a profile picture maybe one of these backdrops will appeal to you. =) Enjoy the pictures and have fun getting acquainted with your SL.
ETA: Check out the sculpted prims exhibition (on Machinima Sim); you may find more freebies.
