Solid advice from StevedOx...I am on a similar progession...seats and harnesses are the best upgrade you can make right now...my $.02
I'll add to that, even without harnesses a race seat will hold you a lot better than the regular OEM seat.
Race seat + harnesses == fantastic! It took me a long time to unlearn clenching and bracing my legs for support and the death grip on the wheel to hold myself in place.
If you go with harnesses, I would add a HNR device (Hans, NecksGen, Schroth, etc) and also the BK roll bar extension - those harnesses hold you very upright in the seat and in the case of a rollover, you need that extra protection/headroom, and in an impact, the HNR device will keep your head from snapping forward.
I don't know if the airbag would deploy back enough to keep a person's head from snapping forward like in the below video, so it may not be as critical in a street car with an airbag... But dang...
