Thanks for the help everyone.
Besically what I did was just test everything out, and to be honest I rushed things a little, but I just wanted to get a quick feel, and see if I had me head around everything (which I now know I semi-half do). I hadn't dialed in any filtration which would explain the short time (?). Looking back on it, I also completly over-exposed my first print, which turned pretty much black, which could be why I left the following prints in the developer for far too short a time.
The 75mm lens that came with everythig is very foggy too. The guy said he virtually never used it, so that didn't help me out much either as I only have 120 negs to print at the moment.
So I'll buy a few books, do alot of reading and buy a new lens post-Christmas then try all the tips you have all suggested and let you know how things have turned out. Fingers crossed I get better results!
