Which one first?

[Faster_than_you]

Hey you all, I have been following this forum for about 2 weeks now, the first day I found the site, I spent about 8 hours reading nearly every single post. Learned alot, well I finally was able to log on today and ask this question that has been running through my head for the past few days.
I have a dillema of trying to figure out if I should get my wheels first or to get my airbag setup. at the moment I only have about 2g to work with. I want to get both eventually, but what one would some recommend first? Airbags to lower or to get my 22" wheels first?(. too big? dont want to go any smaller than 20's) very hard decision. I am also trying to figure out if I want to get a f-b system or to get a f-b-s-s system. I know that some say it helps around corners if you get the f-b-s-s. but wondering what the different components are that cause you to be able to s-s control. is it the ports out of the tank?
also anyone know of a 4 bolt main converstion kit for a 454? I know they are readilly available for the 350's. but a machine shop I trust says that they have never heard of such a kit.
I also bought a custom auto interior book a couple of weeks ago and they use chipboard for there interior planing, anyone know were I can get some, home depot and lowes doesnt carry it.
well I will try post a pic of ms. marry (my truck) tonight. thanks!
I also have a couple of months to decide what I want to do, truck in back home in washington state.
I also am in need of lwb bed, I checked with a junk yard and they said 400 for there rusted, pos beds, I laughed and walked off. I have a 92 bed on the back, just needs some trimming down to make it look like a better fit.
