Imperial Guard Army List - First 500pt attempt

After visiting my local store and a few folks at work mentioning it I thought it might be a good idea to get a force together as something to work towards and also as something to help me relearn the rules.

The force is designed as an initial starting point - though obviously if its that bad I'm sure I could start afresh - as something to buy some models for and build up. Its also my first proper foray in to list building and could be the road to disaster.

so without further ado here is my first all rounder list:

As you can see its a bit of an Air Cav force designed as a bit of an all comers killer. I fancy playing this in the local store in their 500pt pick up tourney as well as against some of my mates.
I know the force may be a bit extravagant so any suggestions on alternatives or changes would be great. I intend to be taking on any force but the most common forces I am expecting are Space Marines, Tau, Eldar and Kroot. Any suggestions on building a good guard list would be great.

Thanks and feel free to feed back.
