Alright, answering (and cementing some answers) to as many questions as possible:First off, yes, they do take your caps if you bring bottles and when you buy a drink there, they will keep the cap 95 of the time. They also won't let you in with a bottle containing ice.As for the "Skip the Line" pass, at the gate you will see a banner that reads "SKIP THE LINE". Go there, show them your pass, and you will be able to go into the concert without having to wait in line. Usually they are indeed laminates, but I have not seen them this year, so I am not 100 sure.If there is rain, thunder, or lightning, the show still goes on. Rain and thunder stops nothing, but if there is lightning, bands will have to wait until it dies down before continuing their set due to obvious danger with their equipment and all. Postponed, not cancelled.For the question about directions from nys/ontario, mapquest is a little fucked sometimes. Use google maps and type "Parc Jean Drapeau Montreal" as your destination. It comes up just fine.As far as I know, it is indeed Circuit Gilles-Villeneuve and yes, you have to walk from the metro to the circuit. There will be tons of people who are obviously heading for Warped so usually you can just follow with the crowd and find your way quite easily.
