Crazee,
For the kind of use you describe, I would say you'd be better off with something a bit meatier than the 190. I've never been impressed by the basic 190 model and cannot for the life of me understand why it is held in such high regard. It's OK, but nothing special. For big lenses (wildlife) or extreme close ups, I'd say you'd be better off looking at the 055 range.
As for supply with a head, most 'high end' manufacturer's do not supply with a head as standard, but often dealers will do a legs/head bundle deal.
Take a look at
http://www.cameraworld.co.uk/tripods...ryname=Tripods for some pretty good deals.
I hate to say this, but, the kind of head that will be most suitable for wildlife may not be suited to macro. Depending on which subject is going to be your main use, pick the right head. Personally, I use a head with 3 separate axes (Manfrotto 460RC) for macro, and a pan/tilt (Manfrotto 128RC) for long lens/digiscoping. Oh, and a 486RC ball head on my monopod. Horses for courses.
