also waiting for tripod info :p
Price, stability and portability are three factors which need balancing here. You can't have all three unfortunately.
For stills, a good ball head with an arca swiss type quick release is probably the most sensible way to go. And for stability, try to get a tripod which extends to the height you'll typically use it at without requiring the centre column to be extended.
Beyond that, I'm guessing for travel you want something that's both light and compact. If you want something light and compact which is also stable with a good head, it's serious money.
On the other hand, you could compromise and just go for a top end gorillapod, and keep an eye out for rocks, benches, railings or branches to get the camera into the sort of position you require.
Whichever way you go, make sure the tripod is rated to hold a lot more than the weight of your heaviest lens/body combined. If you buy the right tripod now, it could do you for countless years - long after the body and even lenses you're planning on buying now are retired.
