If you are really set on pure melee dps, then go for broke and change your stats to take advantage of Divine Might.
Something like this:
S 16 +3 tome +6 item/DP + 5 level ups = 30
D 15 +2 tome +6 item = 21
C 12 +2 tome +6 item = 20
I 10 +2 tome = 12
W 8 +3 tome +3 enh +6 item = 20
Ch 17 +3 tome = 20 (Divine Might 4)
This is assuming that +3 tomes will drop unbound next Mod (a pretty safe bet). If you are not going for a decent DC anyway, make your wisdom score your dump stat, using mana for heals and buffs. Divine Might 4 is equal to +16 str.
Go dual rapiers for the +2 to damage/to hit from racial enhancements and the free proficiency.
Total damage modifier:
1 rage pot
2 racial enh
+34 self buffed
8 bard song
+42 raid buffed
...Not too shabby for a pure cleric.
Skill points into concentration and balance.

As someone with four capped clerics, three of them melee oriented, I'll echo the others' sentiment: a true battle cleric heals and fights. Quicken with mass cure x is usually plenty. Not doing so is a quick trip to the black list on your server. Get a torc, a few con op items, and go to town.
