Help a new guy out?

[Helios001]

Hey everyone. I recently picked up a 1986 Celica gt as a present for my girlfriend. I'm doing some minor maintenance to it, and now I'm on to changing up the plugs as I don't believe they've been done on this car for several years now (no way of knowing for sure, but they did look dirty as hell)
I asked the service guy at the local canadian tire what plugs he thinks I should get, and he ended up selling me these NGK IX Iridium plugs. BPR5EIX-11
I tried to read up on them and it was all information about the heat range of the plugs and what not, and to be honest, I'm no car guy, I only really know the basics.
Are these plugs in the proper heat range for my Celica? if not what do you suggest I get?
Thanks for your time.
Troy
