Fianlly bought it! need to learn a lot!! air ride and rust question

[hotrodv]

Finally after have looking for months I've take my decison and deicide to bought this e c10addicted 64 from Berlin! The owner bring it to me trough 1200km on a trailer and under the snow!!Amazing guy!!
Now it sit in my garage, I've still not had the possiility to try it well but I love it! Find out some history from the builder to the previous owner in the Usa, nice.

Now I think I will need help and I've start reading a lot..
The truck air suspension work good but I've noticed that it raise up and go down very slowly compared to video I've seen of truck and cars that go up and down very fast, it has a viair compressor from whaat I know, what I'll do for have it moving faster? new compressor? bigger diameter hose? I really dont know nothing about this thing and you wont find lot over there..

Another thing is the cooling system ,from what I've seen it heat up very fast, did I need maybe a electric fan? different radiator?

Also the start of the engine is a little hard, it take sometimes before stay on regular, it doesnt have choke and has a mechanical fuel pump, any tips?

I apologize for the probably stupid answer, just need to learn some basic I think..

and..some pics!
