orz if you plz

I'm new here and I'm really impressed with what I've seen. If any one could please help me out with this:
私も一緒にしてあげる
I understand the first part roughly, but what does shite ageru mean? I'm familiar with suru, te-form, and ageru seperately, but the combination is lost on me. The context is one student is telling another student that he shares a problem with the other.

Thanks for your time.

I have one more question actually,

本当にしてくれるの？

I know 本当に but the してくれるの has me guessing.
