Hey peoples

Just become the proud owner of a V plate 2.5td elite. It's a lovely old thing, a manual aswell, and in very good condition overall. I've got a couple of quick questions;
Having never even owned a Vauxhall before, firstly where is the OBD port on these, I've got a cheapo OBD2 reader off the bay and want to see if it will talk to it.
I am also looking to blank off the EGR pipe from the crankcase, is there a guide on here how to do it?
Thirdly does anybody have any good advice on what the best chip would be to use with this engine, it's ok on boost but as you all know a little dicey when overtaking on an incline etc.
It's a curious pearlescent purply blue grey colour - does anybody know the name?? I'll get some piccies up later
