First of all, the numbers you have posted are basically meaningless. You need to go and do a meet ASAP to establish a baseline.
There is nothing wrong with going into your first couple of meets in belt and wraps. That is how we always start lifters. We let them get 2-3 meets in like that, depending on their strength level, and then start them in gear.
A kid your size (181) I would want to see at least a 300 squat and pull and a 180-200 bench under meet conditions before I started putting you in a suit and shirt. Some kids get there real fast, some not so quick.
Since you are, in all likelihood, already there, the best advice I can give you is go do a meet without equipment and then pick another meet, buy your equipment, and start training in it.
Typically, there are two mistakes newb lifters make as it relates to gear. The first is not training in it enough, the second is becoming too reliant on it.
Bottom line, you need to rep in your gear. Especially bench shirts. I would state a solid 5-6 weeks in the shirt and 4-5 weeks in a suit and wraps. Minimally.
We try to never get more than 3 weeks away from our gear. In other words, we will use it every third week in an off season training cycle.
In regards to what to purchase and what to expect, WEC gave pretty solid advice.
I would recommend probably @ a size 38 Centurian, and 42 F6. The whole thing about an F6 being for a big archer is nonsense. Accross the board, it is an easier shirt to control. Obviously, the manufacturer can help dial the size in, but buy the loosest fit.
We alter our own gear, so we start a lifter off relatively loose and then tighten it up as they get stronger and more confident. There are tons of competent lifters around you, so find some and you will probably find someone who has a clue about alteration and can refer you to a tailor to get the job done.
Honestly, I am suspicious of your squat depth because, unless you are a squat freak, your conventional pull should not be that far behing your squat, unless your squats are high, and/or you stiff leg your pulls.
In fact, I would expect your raw squat to be lower than your raw pull. You may be the exception, but I would take a close look at that.
Bottom line, there are tons of meets in TX, so pick one and do it. Don't change a thing for the first one, except get some knee wraps.
Get that one under your belt, and take it from there. Nobody cares what you total at your first meet. It's just like your opener. Nobody remembers where you started, but you want to make sure they remember where you finished.
What's most important is surviving your first meet, and ideally going 9/9.
