Actually, you can throw all your resources into the pot and get a +9 hit bonus as a monk (+5 dex, +1 level, +1 implement, +1 Accurate implement, +1 Staff Expertise).
But then, you can do the same thing as a cleric, too -- +5 wis, +1 level, +1 symbol, Proficiency (Accurate Holy Symbol -- or Undeniable if you're mostly attacking Will and your prayers usually do damage), Versitile Expertise = +9. If you're restricted to PH1 prayers, you have some incentive to bump up your hit chance as a laser cleric--as your at wills both target reflex, so you'll have problems hitting lurkers and others with a high reflex (but should be able to easily hit brutes). If not, you can mix it up by grabbing Gaze of Defiance instead of Lance of Faith -- so you can use Gaze against foes who have weaker wills, and Sacred Flame against slower, more strong willed foes. Or mix a ranged attack (probably Sacred Flame, as SF is awesome) with a weapon attack that's based on Wisdom; there are a lot to choose from now. There's even the super-accurate Storm Hammer, which gives up riders for being a weapon vs Fort attack.
You shouldn't have any problems at all hitting as a wizard, frankly. Wizards usually target 2-3 foes with each attack and have relatively few reasons to not have an Int of 20, so even though their hit bonuses are the usual implement sorts, they can easily match the hit rates (though not the damage--usually) of a Ranger. Grab Enlarge Spell when you can, as that makes it much easier to get multiple enemies in a burst, and don't fear hitting a friend if it means hitting two more enemies (particularly minions).
I've generally found the character types that I have problems hitting with are my crossbow artificer (as I didn't have the feats to get really accurate between making sure I could use my bow without losing actions) -- particularly in comparison with my blaster wizard and avenger, who very rarely go a turn without hitting something.
Ah, a pacifist. that explains a few things, as does your load out of all attacks vs reflex. Keep in mind that as a pacifist, your job isn't really to hit stuff or to do damage. but keep mind that Astral Seal is a Wis + 2 vs reflex -- so your attack on that even as-is should be +8.
