Don't worry about the gear at first, if you have the 3 guns, that's all you really need. Focus on going and just having fun, being safe, and learning the sport. I shot my first match with a stock benelli nova, sig p250c 9mm with only 2 mags (that hurt in a stage), and a 3G upper with a 1-4x on a RR Lower. .Didn't have any fancy belt, mag holder, or even shotgun shell holder had to use my pants pockets (the 28 round shotgun stage sucked lol). My buddy started with an 870, Ruger SR9C, and an iron sighted bushmaster. Use the equipment you have until you feel it's really hindering your performance or keeps you from being a better shooter, then upgrade.
