most times these questions are asked in recording gear or Microphones & Setup section, so there may be some results in there for you to review.
Going on the terse info provided, check out the dynamic cardioid Sennheiser MD46 microphone and maybe a recorder like the Sony PCM-M10. The mic is mono and the M10 only records in mono so look for a XLR female to 1/8" stereo male cable.
Treat cardiod mics like a flashlight, it won't magically pick up audio if you forget to point it at your subject. Wear headphones so you know how not to create handling noise.
