I gave you a Llama Badge with the Give option (top right). Llama Badges are free to give, they don't hold any real value (except they're rocking freaking LLAMAS!), they're just for fun. You can give or recieve Premium memberships though, or Points (which cost, and can be used for money all over the website, to buy prints of artwork or shirts or stuff).
Every little window you see on your page is a "widget". Newest Deviations is one, Journal is one, deviantID is one, and so forth. If you click on the top right of the Devious Info-window, you should be able to add some cool info about yourself, that might be a start.
A deviantID is usually a fun, cool or quirky picture that represents yourself, and Journal is your own personal blog that will be shared with your subscribers (me!).
If you need overall help, click the arrow on the absolute top right of the page, and if you want some stats about your membership and page, click the three grey areas at the top of your profile (mouse over where it says Alex7000, Male/United States for instance, then click).
That's about it man, let me know if you there's anything else you're wondering about!
