Looking at your account, you have a bunch of codes that may still be valid, sitting in your email Inbox from when you signed up back in September. If you can't find the emails from general@codenameentertainment.com, then you can put in a help request using the "Help and Support" link in the white text at the bottom of the game and we'll see which ones still work.
You may not have enough Idols to do all the guaranteed Jeweled chest objectives, but you can play the Easter Free Play as many times as your Gumdrops allow, and reset to try to get Easter Jeweled chests. And very cool that your birthday is coming up. :)
To recruit the Easter Crusaders, you need to reset the world with Nate Dragon once you beat their objectives. You can reset, or possibly abandon your current objective, to start the Easter objectives if you have enough Gumdrops.
