I don't use quartz in my builds at the moment as I haven't had a need to do so. However, I do go to the Nether for glowstone as I do go through a lot of that very quickly when building (either in glowstone blocks or redstone lamps).
To compromise on the kits idea - I would suggest a nether quartz kit of 64 blocks with a reasonable cool-down time (i.e. not too short, but not too long). That way if you want to use a lot, you'll either have to save up kits, or go mining for the extra (but having the kit wll make you less reliant on the Nether).
The same could be said for Glowstone - although I'd make that the same as a TNT kit (something like only 16 blocks with a 10-12 hour cool-down time).
Oh and as for regular resets - I'm sure that can be set up with a script - so no-one has to get off of any seat to do it
