What type of cable is suitable for an RS-485 interface?
There is some quite useful information, and a link to a specific forum for RS-485 at www.lammertbies.nl/comm/info/RS-485.html The last time I used this, we ran it over standard Cat5 and it was fine, with close tolorance 100ohm terminating resistors, but you may want to consider shielded cat 5 if the area is prone to strong [...]

Will a hot row facing a wall cause hot spots?
The wall would just stop it from the heat going away straight back further. You would need a parallel flow of air movement in the “hot aisle” so the “hot air” won’t just sit back against that wall. You would need to have vents to suck in that hot air, otherwise it would just sit [...]
