50mm is the focal length. It is a prime (no zoom). Primes are usually faster and sharper. The 1.8 is the f stop. The lower the number the faster the lens (it allows more light in).
I highly recommend getting Understanding Exposure by Bryan Peterson

It explains everything well and is easy to understand. Plus, visit the photography board. They are EXTREMELY helpful and very knowledgable.
