Well, before I can get too specific, I have to have two questions answered. The main question is, "Dex or Str based?"
No matter how you cut it, you'll have to hit at least 15 dex for the TWF feats (unless you were just going for TWF, but regardless). Since you're going as a melee cleric, you probably don't have a huge focus on casting. For this reason, it's plausible to start with 16 Wis, rather than 18 Wis. This saves up 6 points; we've used 18 at this point. For survivability purposes, I'd recommend starting with a 14 Con. A decently equipped Cleric whom started at 14 Con ends up with 400-450 HP, both plausible numbers.
So, here's where your decision really comes in. Sitting at 8/15/14/8/16/8, we've burned 24 points. If your Str based, it's completely pragmatic to put the remainder of your points into Str. This hits you at 15/15/14/8/16/8. Assuming level ups into Str, you're going to sit around:
Code:
15 base
5 levels
6 item
3 exceptional
3 tome
1 litany
1 human enhancement
-------
34
That's not too high, and YMMV.
Dex based is a little bit different. You probably still want to take power attack, so you'll take at least 11 Str (11+2 for Power Attack's pre-req). 14/16/14/8/16/8 is a perfectly reasonable stat distribution if you're more into being balanced, since having 11 Str and dumping the rest into Dex ends up with 11/17/14/8/16/8. But, your character.
Feat choices are pretty simple, assuming human:
1st: Empower Healing
1st: Extend Spell
3rd: EWP: Khopesh (Str)/Weapon Finesse (Dex)
6th: TWF
9th: Quicken Spell
12th: ITWF
15th: Power Attack
18th: GTWF
You could swap out Khopesh for Toughness if you're STR based. Multiclassing into a 17 Clr/2 Mnk/1 Ftr is a good path for this build; it opens up 3 feats. If you do this, you can grab Toughness, Lightning Reflexes (to help your Evasion), and Maximize Spell (by using Power Attack as a fighter bonus, for example).
Hope that helped a bit. I'll try to answer any questions.
