you should put all stats in str for sure

that's right that pure str axe barb are better but you're so close to the mq, just put all in str and it should work

with your stuff, it should be okay playing catas

if you want to go solo tho, you'll need a better weapon ( axe 120+ee ) et a better armor ( 130+ ee )
it just depends on how much fg you're ready to invest and what you wanna do
