I'll try get you some part numbers and a prices tomorow mate, the procedure you mentioned above is fine only other thing to do is remove the V belt or what ever you wana call it and spin the power steering pump by hand for a while to
"bleed the pump" or you will get a nice steering shudder for a while. I'm prety sure there's a o ring around the pipe which could be where your leak is coming from (haven't done one for a while so details are blurry).
