Cat5 cable has four twisted pairs. You need to use a pair of wires that are twisted together for each signal. Running signals over "split pairs" is a recipie for maximum interference.

Cat5 comes in solid copper (for permanent installations) and stranded copper (for patch leads and things that get moved). You will probably want stranded.

Shielded Cat5 isn't particularly common. Cat6 foiled twisted pair is pretty common, but Cat6 properly shielded isn't too common either. In the data world people who don't have interference/crosstalk/grounding/security problems use Unshielded cable, and people who have interference/crosstalk/grounding/security problems use fibre.
