Wow did I derail my own thread with the LW comment or what...
Anyway I agree with this line of thought:
I think you'll do fine as a melee druid with those stats.
For other possible feats instead of summoning focused, I'd suggest Companion Spellbound (share spells out to 30ft away) and Improved Toughness. I know those 2 feats have saved my melee druid practically every encounter - a d8 HD just isn't enough when the DM throws really heavy hitters at you, and it's good to have the flexibility to buff yourself and your companion without keeping the companion within arms' reach.
I'm going to ignore all pre-tenses that I ever wanted to be a spell caster and just imagine that I'm playing a fighter with some cool abilities. As long as my wisdom is high enough to cast the spells of that level I'm going to basically ignore it.
I'm grabbing Heavy Armor Proficiency and Improved Toughness at 1st. 3rd Level I'm gonna get shield specialization (heavy) instead of Tower Shield proficiency. 6th is of course Natural spell. Where would you guys go from there?
9th level and beyond:
Action Before Thought ----> Pearl of Black Doubt
Multi-Attack ---> Improved Multi-Attack
Lions Pounce ---> Great and Small (Complete Champion)
Power Attack ---> Improved Sunder/bull rush ---> Shocktrooper/combat brute
