yes get a heater now, they are not too costly. You will want to wait for several months on the anemone. They need an established tank to really blossom. You risk killing it in a new tank and that will cause such an ammonia spike that everything in your tank will be dead as well. Shrimp are great, but are also very fragile and need very consistent parameters. I would wait a couple months before adding them. Avoid the banded shrimp. Feather dusters will be fine after about 6 weeks or so.
As for fish, an ocerallis clown will do fine with a firefish or gramma. There really isn't much room for fish in a 30 gallon. The room seems deceptive til you stick your live rock and sand in. Good luck.
