Hi Raymond,
I saw your original post yesterday before it got edited/deleted, so a couple bits of advice and questions on what you'd originally posted...
You don't need a dry-tooling specific rope. For easier top-roping and leading, a standard single rope is fine. As a lot of the tooling venues are on less than pristine rock, at thicker rope is probably a good shout.
For ice climbing and mixed winter climbing, it's a different story. You Ideally want fully dry-treated ropes. What sort of rope (single / half / twins) depends on the situation, but I use 2x60m triples for flexibility.
For dry-tooling, assuming you'll be wearing crampons, you're best off learning on top-rope rather than low traverses or boulder problems. This is because falls can be unexpected and even a short ground fall can easily trash your ankles while wearing crampons.
Also while there's a lot of overlap between dry-tooling and ice-climbing, there are some differences too. So if it is ice-climbing you're really looking to get into, it's well worth a visit to either the Ice-factor in Kinlochleven or the Snow-factor in Glasgow (or given where you're based, flying to Norway for a trip/course). Closer to you, there's also the Ice wall in Covent Garden, but having been to the sister ice wall in Manchester, I wouldn't recommend it.
