First go at all grain...batch sparging...efficiency?

Gigemags05 said:

I've decided to try my hand at all grain. For my first batch, I am going to brew a Rogue Hazelnut Brown Nectar clone.

I'll post the recipe below.

I am using a cooler mash tun with a stainless braid (just like Fly guy's pretty much).

I am going to batch sparge.

Questions:
I bought the grains already, not really knowing if I needed to adjust the recipe for efficiency. Is there a rule of thumb on how much to adjust for batch sparging vs. fly sparging? Is this recipe probably set up for fly sparging?

Also, with this being my first AG batch, how am I going to guesstimate how efficent my mash will be? What is a good goal for efficiency?

And lastly, if I do have to adjust the recipe, could I just lessen the amount of wort I boil and make a slightly smaller batch? I already bought the grains and don't really have a means of getting more. I just don't want to have a bad batch on my first AG brew.

I really appreciate any help/advice.
