I think either way is correct. Most of the members of my crew I train with bench on toes with heel up. They are also lifting mostly in gear. I prefer to bench with my heels planted. It sort of comes down to which federations allow heels up and some don't. My crews fed, GPC, allows heels up.
I would bench on tip toes for your arch, and then really press your traps against the bench which will help you remain tight and help you naturally create leg drive.
