Hi Paul and welcome to the forum. I'm afraid I don't know the model in question although there are some, cough, cough, 'older' members here who might be able to help there.
The first thing you can do is have a look through the obvious suppliers for fixtures and fittings. Getting hold of a copy of the magazine is handy there as the big ones all advertise there such as Howes and Cornwall Model Boats. There is also Shapeways but the stuff there is all fine 3D resin so maybe not robust enough for operational models. The motor might be suitable but some pictures of the model would be a great help so we can see what kind of hull it is.
As for electronics, to keep it simple I would suggest the following:
1) Speed controller – call Mtroniks and ask them to recommend a speed controller for you. Probably either the Viper 25 or the Viper 40. This depends on the motor you go for. If you decide to go for one with a BECC you don't need a separate receiver power supply.
2) Radio set – go to Howes and buy thier £40.00 2.4 ghz, six channel set with included receiver.
3) Steering servo – either Ebay or go to Servo Shop.
4) Battery pack – Component shop will advise you. It depends on which motor again and therefore which voltage you decide to run it at. If you have a large hull a 6v or a 12v lead/acid battery might do you but, if smaller possibly a 7.2v Nimh pack. Component shop also do chargers, wire, connectors and fuses.
That should be a start. Pictures really needed for more specific help.
