I am going to get a tow bar with electrics  fitted to an  Omega 2,6 v6 2003  saloon if I buy it.   Any do's and dont's.

Yeah make sure you also LPG it or get the 2.2 diesel version.
Thirsty, that is if your going to pull anything heavy like a caravan
The reason I keep my TD for towing duties

Depends on your wallet & if it matters to you whether you want it on show.
Cheaper towbars are 2" box section that's bolted the the underside of the car and come with a 2 bolt flange type ball. OE Bosal have a large plate inside the boot floor that all the major bits hang from and usually have a swan neck bar and look a little neater than the box section type. Detachables are similar to the Bosal ie there's a plate in the boot floor again and the ball is ..... er  detachable 
The 12n electrics are fed via a socket/plug in the back of the car, although you'll find that towbar 'specialists' will want to cut this off & to use the varios supplies. Vauxhall did wire the car up to enable you to extend the brake light check to your trailer via a 'relay' that lives behind your glove box and feeds the yellow/black wires at the above socket/plug.
12S socket requires a 12 volt supply for the fridge switched when the engine is running, you can use a voltage sensitive Smartcom relay (this is similar clicky) Just check the requirements of your caravan as later caravans (97/98 on?) have a 'habitation relay' in them that switches a permanent 12 volt supply from the car to use to charge the battery.
