Yes, you would be running rich at idle, and lean under boost. Not great, but it all depends on how rich, and how lean.
Pull the spark plugs and look. They live in the engine, and they 'know' what's been happening. Plugs should be a light grey. If you see the ends of the plugs overly worn, that can be a sign of burning. Or clumps of crap welded to the plugs. Again, not great.
At a minimum, I'd plan on replacing the plugs. Cheap (very cheap!) insurance. And an oil change wouldn't hurt - you've probably got more in the way of bizzare combustion products, and those end up in the oil, and use up the buffers in the oil.
Other than that, there isn't a whole lot you can do. Unless there is something wrong with the FPR, simply leaving it not hooked up won't hurt it, not unless a spider decided to live in it or something equally bizarre.
As to upgrades, I'll leave that to others. I have enough trouble getting things to work stock.
