Hi Googies,
I assume its the new shape (altea style) Toledo you have.
Cant tell u anything about strut braces, but the headlamp bulbs are H1 main beam, H7 dipped beam. Not sure about the fogs, commonly H3 on most cars now....its in the owner's handbook anyway.
Dealer fitted a 'Witter' towbar to mine when new. It a strong but not very beautiful looking thing....unfortunately not the sleek 'swan neck' type but instead a slightly LandRover looking 'flangeball' hitch. Might be good a t pulling a huge caravan, but a bit ugly for a light trailer.
Try to get a swan neck type if at all possible......'Brink' do nice ones....I see you're in Ireland.....try looking at McCabe Ironwork's website...they make very good towbars at much lower prices than the big Euro makes...and deliver COD within Ireland too. You need to call them for the price.....

Expect to pay anywhere between 200 - 300 euro for a decent towbar (without fitting or wiring)
The bigger
problem is the wiring...because of ECU controlled overengineered light control, you need a 'multiplexer' box to make the connections for the 7 pin plug. These aren't cheap.....through a dealer they retail for somewhere around 100 euro...you might locate them cheaper elsewhere.
So, allow at least 300 euro for the parts, if you want professional fitting, add another 100 - 150 euro (add VAT too !) and you wont have much change out of 500....maybe 450 if you are lucky.
