How much mobility do you need? The 17" can be unwieldy if you move around a lot each day. Personally, I think the 15" is a great compromise, and if hooked up to another monitor while at your main desk you end up with the best of both worlds.
As for Leopard - I think it's really a money decision rather than performance. Tiger is fantastic and few are expecting huge performance or stability increases with Leopard. If you need a new Mac now, get it and then grab Leopard when you have the cash. If a new Mac is not an immediate need, perhaps wait.
