erm, multistrike when you're not even samurai or later? interesting i personally avoid anything in the dark red. Pink is fine if it's an ability you like
For group i'd be using bottoms up, knockdown and powerstrike with fighter
For solo i'd be using knockdown, retribution and power strike with barb seeing single target damage is much more important, also great versus well mobs

the only time i suggest fighter over barb for solo is on the first climb as easy mode is on = max of 2 mobs, so maxing power strike first is best. to toggle use /set easy 1 or 0. If you're solo'ing you're basically item hunting and imo better off with it off.
oh and to directly answer the other 2 questions:
If you're tanking in group 75-85 vita rest into strength If someone else is tanking then all points into strength.
Solo i'd still recommend 75 vita myself.
No ratios. Just put all points into strength once you've got the vita (i usually get first 20 points into str just to 1 hit all the starter mobs then vita to 75 from level 10-xx)
3. Very solid set, you'll have no issues, you'll need to use the tank armors imo.
When you get to monk, you'll need a dex set + staff set (no point in buying daggers as they'll be 5x as expensive as staffs)
