I have the HDV version of that head and it's pretty good for a decent size spotting scope, but not ideal for photography. I used to have a Manfrotto 190 but (in the UK they are cheap and cheerful) I feel you will want something better before too long.
A friend of mine has one of these (http://www.feisol.net/feisol-tournament-tripod-ct3342-rapid-p-30.html
) which we both find very good and remarkably light. I have used it with a Canon 300 F2.8 + a 2 x extender and found it OK - not as good as our Gitzos but very usable. This Feisol is a bit more expensive, than the Manfrotto, but it is significantly more rigid and you will be happy with it for longer.
As to ball heads. most recommend rather large (and expensive) models due to their superior lockup and lack of droop/creep. I agree with this but there are a few exceptions. I have a Triopo RS3 (don't know what it's called on your side of the pond) and love it. It is light (270 grams) cheap (30 GBP), you need to add a QR clamp (10 GBP) and it holds any Canon lens happily - well almost, I don't think it will cope with a 1200 F5.6! However it will cope with the likes of a 600 F4 or my Canon 800 F5.6. I am not suggesting using it for these lenses, but that sort of lockup means zero movement (on a good tripod) with more normal lenses, which is so much less frustrating when you have the framing "Just Right"!
