'Clean Installing Lion' and Backing up

What are the easiest ways to do this?

My problem is I keep getting disk errors on verfiy disk. I boot into the installation CD, fix the errors but new ones pop up after a week or so.

I have read a few guides on how to clean install Lion but they all seem different and confusing... I just want one clear concise guide.. surely it can't be this hard?


Also, backing up wise.. does Timemachine suffice? I want to keep my Dropbox folder, documents and Itunes. Does time machine save all this jazz and fine enough for me to grab it back? Any hints/tips on time machine would be much appreciated and getting my itunes & docs back.

 

I dont know my options tbh....

Programs like Itunes are taking 20 seconds to load.

I just want them to work. I've tried repair disk/permissions... now I'm going for the 'clean install'.

My plan was to format then just use time machine to grab my music... copy+paste it to a folder, then get my new itunes to sort it all out.
