Question about attack and strength.

Currently have fully quested 50 attack pure, looking to get 60 attack, what other quests would get me to 60 or close to 60? Or is it full on grind from 50 to 60? Also, 90 strength atm and looking to train it to 99. Would NMZ be a good place to still train or is there another method of training somewhere else?

thanks in advance
