Code 32 problem and some other issues

[toebab]

Hi there,
I own a 89 Safari and live on Aruba. Unfortunatly the GSM/Chevy dealer on Aruba has the intellectual capacity of a palmtree (no offence to palmtrees ofcourse!) therefor I have to take care of the minor issues that occur driving my car.
Since I'm no mechanic, but have two functioning hands, I've decided to service my car, and take care of other annoyences that came up.
Well, here's the list of troubles:
=======
Code 32 Service Engine Soon. I've got a Chiltons manual, but I just cannot find the EGR. I did check all vacuum hoses I could find, and found some of them in really bad shape. These I will replace, but I also found a (to me unknown) device with something that looks like a connector for a tube. Except there is no tube nearby.
=======
When the engine is warm, it starts running worse. Idle speed is ok, it even runs normal during idle. It feels as if both airco's are switched on, except they are not. I even removed the fuses to make sure there's no shortwire that could switch on the aircocompressor by itself. No cure.
=======
The coolingwater is in the expansion canister is really dirty. It's like rusty water with gum in it. The fluid in/at the top of the radiator was dirty as well.
So I started to flush the cooling system to find out that most of the radiatorfluid was clean/clear. I'm not sure this is really a problem, it just surprised me. The car does not use a lot of oil, and the oil is normal. The car doesn't smoke either (nor white or blue)
=========
To make it a bit easier to understand I made some pictures of the devices I did not understand and put them on: http://www.toebab.com/gallery/Safari

Could someone please please help me out or give me more info?

Thanx in advance.
Enno
p.s. I know the engine looks really bad with all the dust and sand, but Aruba happens to be a sandy/dusty island. Some roads are still dirtroad.
