G/W Aggro tips?

[Everett]

I'm building a g/w Aggro. It's almost finished and here's how it's looking

4x  {Temple Garden}
4x  {Sunpetal Grove}
10x {Forest}
5x {Plains}
4x  {Rancor}
4x  {Revenge of the Hunted}
4x  {Selesnya Charm}
4x  {Loxodon Smiter}
4x {Wolfir Silverheart}
4x {Silverblade Paladin}
4x {Strangleroot Geist}
4x {Arbor Elf}
4x  {Avacyn's Pilgrim}

Sideboard so far is
4x  {Centaur Healer}
3x {Oblivion Ring}
3x {Naturalize}


I'm not sure what else to put in the sideboard and I'm thinking about replacing the {Strangleroot Geist} 's with  {Boros Reckoner}. It's my first standard deck and it works pretty well agains naya humans and naya Aggro, but I'm not sure what to do about control or burn decks. Any ideas?

I meant to put this in standard, sorry guys ignore it.
