Channelized means multi-channel as it is, so no, you wouldn't need two for one emitter. Power supply upgrade for receivers? Did you forget AESA are multifunction, because the EW receivers/transmitters are all AESA.Did you forget AESA are multifunction? Through array choreography, two different signals can be emitted at once using two arrays separated using software.
I'd trust Boeing, who were part of the F-35 program, than just some guy on the internet. Makes sense eh? They in fact made it part of their official presentation, ie, the F-35 does not have any real electronic attack function, "so buy the Growler".
Well, the F-35 doesn't even have that.
Boeing have nothing to do with the EW system, in fact they have nothing to do with the program at all aside from the failed X-32 and their subsequent butt-hurt. Exactly, propaganda, come buy our aircraft. Their claim is demonstrably wrong, as shown in this tweet. In fact, electronic countermeasures can include jamming, attack is a higher level jamming function.

Says who? Boeing? May as well ask Dassault. May as well ask my ar5e in fact.
The radar is separate to the ASQ-239 EW system. Different company NG - APG-81 Radar, BAE - ASQ-239 EWS.but only in X band. It helps, but it's not enough.
