Click the Add Page to MySite link in your left menu and add yourself a web page. That will add your profile to the mysite list. Plus it will be a great place for you to continue your education with how the site works. Any images you need for your page you can get from your photo albums or you can upload any other images to your "My Images" list. It allows you to upload an image, give you the address for it, and use it within your site, or any other pages on the website. These can be smaller pictures, icons, or whatever jpg images you need or want to build your web pages with.
If you don't know what you want to write or make a page about, check out mysite for ideas...
Also, with the video I posted above, with that, I assume you'd already have your video uploaded to your account. If not, just go to your "My Videos" page and click the upload new video link at the top right of the body of the page. Click the link, select browse, and upload your video. The system will upload and process the video into the site in realtime. Once it's done the upload page will go back to the form to upload yet another video. If you have no more close the window. Refresh the my videos page and you'll see yours there. At this time you'll be able to title it, give it keywords, set who's allowed to see it, select the appropriate album, and give it a description. Then save it and it will update.
Once you've done this everyone who you've allowed to see the video will be able to see it. Also, just below the description field in the form is a text area box which will give you a nicely written bit of code that has your title bar, video, and description all ready for you to paste on any web page you want within the site.
I think this video feature is really quite fun.
