Help with garage design!!!!!!! Ready to drywall..

[iluv69s]

I,m getting ready to drywall my 24 x 40 garage...I have the typical restoration type tools and equipment...mig...plasma cutter...lift...rotisserie..compressor,etc......I' m going to pipe air throughout the garage from the compressor that will be in the attached shed..can i use copper pipe? What else should I NOT forget to install?? Any good ideas?? Pics???..I'd rather learn from others mistakes...or experiences...Thanks in advance..How about flooring material?? I thought about the flake type paint..but with the welding,etc.?? I considered a thin plywood for the walls also..Instead of drywall...easier to attach stuff??

Any ideas would be great...thanks again!!!
