Good choice. I found it easy to memorize and retain, unlike most of Rachmaninoff's music. It does require finger stamina but that will come as you work on it.
Some pointers:
Differentiate clearly between p, pp, and f, ff, etc
The middle section requires a strong thumb melody in RH, but make sure all the RH notes are played. The middle section needs to flow. As my Russian teacher said, "Imagine endless fields of grain." Wonderful image!
There are some big jumps. Work hard not to delay in changing positions.
Listen to Rachmaninoff's recording of it. He makes a lot of big tempo changes that I don't like.
All the best,
Ned
