I suggest that all vehicles should have a reduced nanite cost that scales with how unequipped they are. For example: no certifications is a 20-30% reduction. This should alleviate some barriers for new players practicing against veterans as well as give transport vehicles an incentive to focus on transporting only (with perhaps an even heavier reduction). In regards to flashes, the cost should remain the same (cheap enough as is). However, spawning a wraith flash should triple the cost. The farming potential with wraith shouldn't be allowed on such a cheap vehicle.
Not at the current state of resources, at least. As it stands I can respawn an MBT 9 minutes after completely depleting my resources, and it's hard for anyone to deplete it in the first place unless you're performing really terribly in a really costy vehicle.
Even with a price reduction for stock vehicles all you'll really be doing is giving certed enemy tanks more XP. My advice is to try when you can to get in a friendly MBT gunner slot that has a halberd (or ES anti-tank weapon). Don't randomly shoot at nothing or aircraft with a halberd all you'll do is piss off the driver. AP tanks pretty much always run stealth so they can sneak up on other tanks for rear shots so try to pay attention to what the driver is doing and wait till he fires if he is stalking rather then steamrolling. any weapons fire from a stealth MBT will reveal it's location on the minimap hence holding fire till the driver gets a tank to ambush.
