The fact we're having this conversation makes you sick.
I wont be selling any of my 3 tickets and I hope other blues dont either. What's to say you sell your ticket on StubHub and then its gets sold on again at an inflated price etc. You could end up getting banned for what £120 or so, it's just not worth it.
Also Escla makes a good point about fellow season ticket holders who sit by you. People you've sat with for years and the first chance of making a few quid and you sell your ticket, to a red aswell it's just wrong.
I imagine most reds will just target a gate a few mins from the end of the game and just storm that. Get in celebrate if they win it, have the camera phone out to let everyone know they were at Goodison when they won the league etc.
