IMO TH10 is the easiest TH to farm DE:
 * You get 3 drills instead of 2, and they can all be upgraded to 7
 * You get a brand new farming troop: Miners! Quite expensive on Elixir but very fast to train and works well for getting into cores.
 * As a 10 you'll be more likely to match with other 10s which will have more drills to farm from and you can loot more from the DE storage (3k instead of 2.5)

As for collectors, upgrading them will certainly pay off in the long run. However, whether or not to prioritise upgrading them depends on your activity level. If you are very active you may as well leave them to be the last upgrades you do before your Town Hall (perhaps also while your Town Hall is being upgraded). If you are not as active then collectors will certainly be a good investment nonetheless; they're still rather cheap and don't take too much time.
