If the cable is being run in an area that also has conditioned air (i.e.
inside an air duct) then you need plenum cabling. If it is all hidden
behind wall board and attic spaces, regular, unshielded is OK. If you
have a high-RF area and are worried about excessive noise, get shielded.
If you are running a data line near a microwave oven, electric motor
(specifically the really audible loud induction motors) then you will
want shielded for those runs. The definition of "near" is vague. Most
microwave oven can cause data packets to fail from about 12 inches if
the orientation is right for the polarization of the radiation leakage.

For 99.5% of all residential uses, standard, unshielded, non-plenum
cat5e is plenty adequate. 

Go buy the cat5 cable tester from Home Depot. It will tell you if the
cable is wired correctly and can save loads of time.
