Problems with WOW after patch!!!!! Help!!!!Follow

Hi,

After this new patch I'm having some problems with my WoW and some of them are really making me sad.

The 1st problem is I cant see myself with any of my chars
The 2nd problem is almost 99% of my inventory items are '?'
The 3rd problem is I'm getting disconnected very often, even more if I'm in a big city like SW/Orgrimar.
The 4th problem is sometimes when I log in I cant see my quest. My quest log just don't show them.
The 5th problem is I can't see anybody cloth/armor. Everybody is naked to me.

Help......I really want to play!!!!!!

I was having similar issues, no quest logs, can't see myself, everyone else is naked or even invisible as well sometimes. I found on teh wow forums http://www.blizzard.com/support/wow/?id=aww01686p3 just disabling the checksum offload property on my network card and everything works great now.
