some noob questions

Hey guys whats up? Im going to be gettin either a b2200 or s10 soon and planning on slowly customizing it. I just had a few questions for you guys.
In your opinion which of the above trucks would be better and why. How much does a body drop cost/how much work is it. In general about how much will an airbag system run? Anythin else u wanna tell me would be appreciated too

Thanks alot
