No, those stats decrease the damage you take.

Or the only thing I can do to increase my aggro is get a better weap and more str to increase dmg?
Yes. New weapons, +str, +agi, +crit and +block value (if you're prot specced) all increase your threat. Now, +agi is fauvorable since it gives both +cirt, +armour and +dodge. Block value is fauvorable over +str, since it takes ~22 str to get 1 block value. If you're not protection, however, +str is better than +block value.
Also, +hit really increases your threat (more so than +crit really). It's often overlooked though. It's ideal to have +136 hit rating (+8.6% hit) but if you have to sacrifice alot of stats to get there it's advisable to make it a lower priority.
