For the OP:
WHM level 1 has a major (whiff) disadvantage (whiff) over other jobs (whiff) (whiff)! Unfortunately the aeroga from all the whiffing does very little damage!

There's only two possible weapons you can equip or just go bare knuckles on it (no skill levels though). The weapons are the key here since you can skill up on those:
Club level is B+
Staff level is C+
Throwing is E
There are no other weapons you can skill up on, so you can't use the weapon-skills associated with them. The problem is to get these weapons to the point where you aren't whiffing all the time , and with the fewest possible trips to the home point!
As it happens, MNK can equip a staff, and WAR can equip a club. Switch to one of these jobs and level the weapon on it! Weapon skill level is roughly 3 times your job level, so to get a weapon skilled up for level 10, you need the weapon skill level at 30. Then change to your level 1 WHM and scare the heck out of those mobs by being able to actually hit them (most of the time that is)!!
As for the weapon preference, that's entirely up to you. Personally I went staff the whole way since level 50+ you will have one equipped full time anyway (Light/Apollos or Dark).
Hope that helps!
