I'll get my book tomorrow... is it ok for a Barbarian multiclass fighter to pick feats that have martial classes in general or fighter as requirement?
You qualify if you multiclass into a martial class.
The pre-requisite is "any martial class" - not "martial power source" - the feats are associated with all martial classes.
PHB193 - "Class feats are also available to characters who have taken a multiclass feat in the class the feat is associated with."
