Since you have Photoshop 9 you will have to make sure the brushes you download are for Photoshop 9 and below. You can't use Brushes for newer versions of Photoshop. Another thing you can look into are filters, as well as Phtoshop Actions, which can alos be used to create backgrounds. To me, the most fun is in creating your own background.
Another thought is to download some Ding Bat fonts, which are graphic files in font form. They also can be used to make backgrounds and the like. I've used Ding Bats on occasion, although more for logo making than for signatures.
I use Paint Shop Pro X, rather than Photoshop, but I assume you can also use any .jpg or .gif file as a background with Photoshop? I usually search for "free PSP backgrounds OR tiles", and I've put together a collection that way. Sometimes I've found backgrounds for "Playstation Portable", but they work, too. Some of the backgrounds I use are from a "National Geographic" photo DVD I bought, which gives me the right to use the photos it includes. The photos can only be downloaded online with the disc in.
I'm just now getting into brushes - they're a lot of fun.
