This is just my 2 cents after upgrading a few sites...
Just upgrade to 2.0.13.1 for now and wait it out for a little longer. There are still some bugs that need ironed out and some module compatibility issues.
After the h**l I've gone through with the MyWebResource site, I'm holding off on upgrading the remainder of my clients until things smooth out a little, which I'm sure won't be long.
As mentioned above, maybe you could study the tutorials while things get ironed out. Your best bet would be to download a free standalone server, like XSAS or EasyPHP, replicate your site locally, then practice the upgrade. Thoroughness will be the key. I replicated my site locally, but I didn't go through it as thoroughly as I should have. BIG mistake.

Insanity can be defined as "doing the same thing over and over and expecting different results."
Stupidity is not a crime. Therefore, you are free to go.
