Upgrading buildings and troops in Clash of Clans is all a matter of personal opinion but one opinion is that building the Town Hall is the most important thing because you can only upgrade things such as the Gold and Elixir Collectors as well as the Laboratory only to a point until it becomes maxed out at your current Town Hall level. After upgrading your Town Hall your Clan Castle should be upgraded until it's at least Level 3 if you are in a clan so your clanmates can send you a Dragon for a single reinforcement which hits hard damage-wise.
