Campmor has about the most bug stuff of anyone. Here is a link to a page showing their bug jacket and pants http://www.campmor.com/SearchDisplay?storeId=226&catalogId=40000000226&langId=-1&beginIndex=0&searchSource=Q&sType=SimpleSearch&resultCatEntryType=2&searchTerm=bugs
Those bug suits are not cool. Because of the fine mesh to keep out noseeums (flying teeth), they do not allow much air in/out.
If you are from up north (I see you are from Jacksonville) and used to camping in woods, that is a no-no in the everglades. Keep as far from woods and vegetation as possible. Camp on points where you get maximum breeze. Deet (25% in "Off Deep Woods") is a good repellent. Personally, I don't use 100% Deet because of potential health problems. You can camp near woods & vegetation in the "winter" months--Jan-Feb, maybe Dec & Mar--when it is cooler or a strong cold front is coming in.
Summer time can be dangerously hot. Some people do camp in the everglades in the summer--kind of a challenge, but you have to be very careful and know what you are doing. Take plenty of water, at least a gal/day. Gatorade and that type drink is a good idea to replenish you chemicals lost during a hot day. You should carry an umbrella or other shade for those exposed points where you will be camping. During the day, you can hang out under trees in the shade with a breeze (& Deet repellent,) but as soon as the sun goes down, the mosquitos will be thick. In the absence of a breeze, the noseeums are always a problem on beaches. You can see my example of a beach umbrella on my post at http://www.hobiecat.com/forums/viewtopic.php?f=70&t=7276&start=255
