I'm not very good at the no of attacks thing, all I know is that fighters have better thac) etc and thus have more chance of hitting a monster and higher number of attacks so that they hit more often. So if your char is a mage (which I assume as you're asking about staffs and considering your name
) maybe you could concentrate on spellcasting and let your fighters do the chopping up parts (unless you're soloing that is?)
About the staffs:

In the earlier stages of the game, the staff of Rynn +4 (Adventurers Mart) is about as good as you can get, later on the Staff of Power and esp. Staff of the Magi are very good. Try doing the Twisted Rune quest
If you're low level and cannot kill liches yet, there are also a lot of good +2 and +3 staves available. Also a good one is the Staff Spear +2 as it requires a Quarter Staff proficiency (and can be used by mages) but does damage like a Spear.
