Thanks! Great idea to get up on the platform, it's a great feeling.
The best advice I can give you is to spend some time setting out a training cycle that'll have you peaking for the meet. Depending on how confident and experienced you are you can either do that yourself or get a coach to do it for you. I've been competing since 2012 (not in PL, but the principles are very similar) so I did it myself. Don't overcomplicate it. Linear progression works great unless you're at least intermediate. I used a pendulum approach because I found the 12 week linear cycle I finished end of 2014 beat me up a bit.
Once your program is sorted, before you start following it get your big three checked for technique. The PTC you're thinking of competing at should be able to do that for you along with coaching and programs if you need.
Once that's done, get lifting and trust the process. About a month out from the meet you'll start to get an idea of what your attempts will look like. Make sure you know your first and second attempts at least a week out so you don't have to think about it.
