Wisdom is what you want for mana and tradeskills, the stat most people agree that a cleric needs. Put every point you can into this...

Strength is useful for two reasons; it affects how hard you hit and how much you can carry. Before long, you will hopefully be in a group and doing more healing than melee, but you will find yourself in melee at first, so hitting a little harder is not a bad thing. Carrying capacity is the main reason for strength, because clerics wear plate and plate is very heavy. Go over your carrying capacity (which is very easy if you have heavy armour on) and you will not be able to move as fast, you will get hit more often and for more damage. High strength means wearing better armour and carrying more loot back to the vendors (important because plate is also expensive) at the end of a trip.

Stamina gives you a few more hit-points, but lots of mana means better AC (avoid losing hp) and healing and damaging spells which make fights shorter. If you are losing hit-points, something went wrong...

Agility is (probably) a useless stat unless it drops below 75 (not an issue for halflings) because under 75 apparently hurts your AC. Dexterity makes weapons proc a little more, but by the time you have weapons that proc and a high enough dex to make a difference, you should not be in melee at all. Intelligence is for robed casters and bards, not you. Charisma makes NPCs (i.e. vendors) like you a tiny bit more, but high wisdom and lots of mana makes players like you a lot more.
