Should I unplug my mains (i thought i did but really can't remember)?

Yeah, if you want to do a sub only measure - and you should.
It's just a good idea to disconnect the mains and get a look at the sub itself through the receiver with the crossover set..
It's also a good idea (even though you're maybe not equalizing), to set the proper target crossover in REW to 80Hz also. You have yours up around 120Hz I believe (from looking at your graph). It makes no difference at this point, but it's nice to see if the sub tracks the 80Hz target line on the graph or not. It's all about gathering information. If you see that you have a perfectly tracking sub and then the sub + mains is wacky, you know where the problem lies......
