Ok, after lot's of grinding my team has these levels:
Typhlosion Lv.68
Pikachu Lv.68
Honchkrow Lv.68
Gengar Lv.68
Golduck Lv.70
Victreebel Lv.70
Leveled Victreebell to 70 on Hiker Kevin with constant trainer rematches, rest wast trained with the E4 but Golduck got so much exp from Lance that he leveled ahead. Going to get 2 more levels on the other ones and defeat Blue, then go trough the E4 one or two more times, and then go to Red.
You guys probably found this out, but if you call a trainer, defeat it, and go to another route/place, you can call again right away and rematch again, and there's no limit.
EDIT: Everyone is level 70 now, I defeated Blue, did the double battle with Clair and Lance (Silver had another awesome quote, and Lance's Gyarados managed to miss 5 times in a row using just Ice Fang, and yes, I gave it a chance to miss 5 times xD), collected a bunch of stuff using Rock Climb(while there's still a load of things around which only require Cut/Strength/Rocksmash, but since I've put Rock Climb on my Typhlosion so I can take my whole team to fight Red and I'm too lazy to go to the PC for my HM slaves those are still there). Right now I'm on the S.S. Aqua for no reason really.
