Just a few days ago I completed the Urgent Quest "2 Monoblos" on MHFU. Bring 10 Sonic Bombs and the materials to make them, 10 Potions and Mega Potions (and the materials to make them as well), 5 Cool Drinks, a Shock Trap and Tranq Bombs if you want, Barrel Bombs (just in case), and 4 Book of Combos.

As for a weapon, forge the Blango Decimator. You will NOT be disappointed (unless you don't like Longswords).
