I am running an Mid 2007 imac 20" model: a1224, + 4GB RAM. Is my iMac capable of running Mountain Lion?

And is Mountain Lion the latest MacOS I should get?

And do I buy Mountain Lion from App Store and burn it to a normal DVD and run the DVD and it will upgreade my Snow Leopard to Mountain Lion?

Or what should I do?

Thank you.:)

The Mid 2007 iMac is compatibile with Mountain Lion, and it's the newest OS. You just get it from the Mac App Store. The directions are quite simple:

Should I upgrade or do a brand new Install? Does it make a difference in how Mountain Lion behaves and runs?

There's no particularly compelling reason to do a fresh install unless you're having issues. I've upgraded to Mountain Lion without doing a complete reinstall on 3 computers without issue.

I just paid $20.99 on App Store and its downloading now :)

After it's downloaded, will it automatically upgrade without me needing to create DVDs etc? If so, how do I install Mountain Lion in the future if needed if I don't have the install DVDS?

You can reinstall from the recovery partition it will create, or by reinstalling Snow Leopard from discs, and downloading Mountain Lion from the App Store again (which it will let you do for free).

I just upgraded to Mountain Lion, and it shows I have 2.59GB RAM free, yet the hard drive keeps grinding away, something which it never did on Snow Leopard. What's going on? Will the hard drive ever stop grinding away? It's driving me nuts! And the screen scrolling is so slow as a result!

It's probably Spotlight re-indexing your hard drive. Yes, it will stop, if you leave it alone (Spotlight, not your computer.) Though that shouldn't affect screen scrolling.
Use Activity Monitor to check what's hogging the CPU. If it's processes starting with "md", then it's Spotlight. IF not, then it's something else.

Yes I think it was spotlighting, it stopped now :)

I would make a Mountain Lion USB.
