Ok, i've had a bit of a look around and have come up with the following. Please make any adjusments or recomendations if i have left something out.
I plan to get an Ikelite Housing #6871.10 with port #5503 which according to Ikelite will fit both the 18-55mm kit lens and the Tokina 10-17mm.
As far as strobes go I think i will go with the #3944.51 Digital Package which includes:
#4103.51 Digital TTL Sync Cord
#4044.1 DS-51 SubStrobe with diffuser
#4086.61 Ball Socket Arm system
Do i need 2 of these packs so i can have 2 strobes which i believe is better to shoot with or will 1 strobe do?
I think that's all, but please make suggestions.
