Please help me make a Fire Giant PC from level 1 [SS}

[gfunk]

So we are starting a new campaign and I like the idea of making a big old thug. We use 32 pt buy and Fire Giants have an initial +4 boost to Str. This is what I'm thinking

Str 14 --> 18
Dex 12
Con 18
Int 10
Wis 12
Cha 8

HP are max for 1st level = 8+4 = 12

I have 300 gp to burn so I was thinking about breastplate and a greatsword.

AC 18 (+5 armor, +1 Dex, +2 natural)
Attack +4 (+4 Str)
Dmg 2d6 + 6

Feat: Power Attack

Saves: Fort +6, Reflex +1, Will +1

So here are my questions,

1) What do you think of my point spread for the 32 point buy? Since Con is very important for a front-liner and since my Str goes up quickly, I choose to make it 18.

2) What feats do you think I should take? At 3rd I wanted to pick up Cleave and after that, I'm not sure. Roll With It? Iron Will?

3) Do you think another monstrous PC is better for a front-line bruiser? If so, suggestions would be welcomed.

Thanks!
