Resources are stored globally, not on a per-planet basis. You only lose stored resources if you lose enough storage facilities to bring the overall max below the current stored total.

Dumping tiny planets can be done by removing them from PlanetSize.txt. Make sure to work in a mod folder, not on the stock data files! But if you do this, you absolutely must edit SystemTypes.txt to remove all references to Tiny planets. Replacing them with small works. If you do this, you can not use Bad HW start, as sometimes a moon will be selected as the HW. If this happens, then the "planet" in the sector will be used as the HW, and will NOT be changed to reflect your race's atmosphere and planet type. Next, you must go into Components.txt, and find the entries for the planet making and destroying components. Decrease their Ability values by 1. They work on position in the file. If you remove Tiny planets, then the highest levels of these components will be able to destroy Ringworlds, as well as create them from Huge asteroids, as the position in the PlanetSize.txt file is now one less for every planet size.

An alternate (and probably better) method would be to modify the entry for the Tiny planets, making their stats the same as those of Small planets.
