I had it set way softer when I first came to the track. When we bounced the bike with me on it, it had a lot of oscillation on the softer settings. That's why the front had to get harder. It's probably a combination of my light weight and the spring's preload not being in their sweet spot. They are not at their limit, but they are certantly close.
Do you guys think I can get by with just reworking the front?
There are a lot of ways to half-ass this, but only a couple to get it correct. Respring/revalve both ends, get the Ohlins inserts, or Spend $4K on full Ohlins shock and Forks.
Depends on your budget, how good/fast you are, where you will ride mostly.
If you are budget limited, then I would start with the rear shock. It's progressively sprung and set to work for a 180lb person, all the way up to two people weighing 300+ lbs.. A new spring is $40-$80, VERY cheap way to get a ton of bang for your buck. Revalving would also help, as would putting a different weight oil in it.
The forks can be resprung for around $80-$150... while they are apart, new valves would be a good idea and again thinner weight oil (it flows faster than thicker weight oil and works better for lighter people).
Do it in steps, with the knowledge that in a few months you will have a Bike that's at least got the correct springs for your weight and should be considerably better than what you have right now, for not a lot of cash.
Of course, you could do all that work and spend money and not like it still, at which point your only options are Ohlins inserts or full Ohlins (or some combo of Penke/Ohlins/other 3rd party shock vendor) and you will have wasted money on the stock suspension that could have gone to the full Ohlins.
