In short cycling is the process of establishing beneficial bacteria in your tank that will break down nitrates/ammonia which are deadly to fish. You can cycle with fish in your tank or without. If you do it with fish it's best of you get cheap ones just in case they due during the process. I'm not sure are fishless cycling, but I'm currently having to do 30% - 40% water changes a day for my puffer tank to keep the ammonia down with the bacteria builds up. You can buy cultures of the bacteria at a pet store and it will help to speed up the process.
I'd recommend researching it. I'm on my phone so typing and describing this is hard and I know I'm leaving stuff out.
If you're getting a 30 gallon tank you can add a few more fish. My friend gave me the tip of one fish for every 5 gallons. By that rule you could get two more. Make sure you know how big the fish will get when adults. Plecos can get about two feet or over!
liveaquaria.com is a decent source to use when looking for that information.
