Well, the zoom on the camera is quite crap.. So I would like to increase that. Also i would like to have the ability to manually focus, like the other big cameras with the huge lenses
IMHO If you want to work it like the big cameras... get a big camera. The amount of money you spend on Tele/Wide conversion lenses for Point and Shoots, is throwing money down the drain. Rather save your money and get an entry level DSLR when you can afford with a 18-200 or the two lens kit to give you that zoom range.
The manual focus on the V3 is via the controls on the camera. RTFM
