its all about practice, like bomp said that compresser will run out of air in no time, you are recommended to a compresser with a hp of 2 or higher, but it should be able to be done with one at 1.5.
for the gun id go for something like this,

next you need a clean dust free location to spray, when i spray mine im going to get load of clear plastic sheeting and build my own spray booth with some scaffolding. but if you have a clean garage with not much in it that would be sutable. Remove anything that collects dust, got round cleaning the floor/walls/celing with the vacumn cleaner, and maybe even paint the floor.
preperation is everything, im not gonna go into this much, theres loads on info on the net,

Remove all old paint if unsure about metal underneath. Otherwise flat old paint.
Use filler to correct any low spots in the panel. You may need to repeat this step a numer of times to get the panel flat.
Sand entire panel with 400grit sandpaper until all old paint is feathered and filler is perfectly flat.
Apply a coat of etch primer to any bare metal; this is a special primer which will burn itself into the metal and ensure that the paint sticks to it.
Apply 2-3 coats of Primer Filler. This is a high-build primer which will help hide any smaller imperfections.
Flat primer filler with 600grit paper. Apply more coats as neccessary.
Examine panel and use stopper on any tiny imperfections, e.g scratches or chips. Stopper is a product similar to filler, except that it is much smoother and easier to sand. Look for the 1K stopper, which comes in a tube and doesn't need hardenener; it's much easier to use!
Flat all stopper and apply a futher coat of primer (normal primer would do here)
Flat panel with 800 grit paper, this will give a perfectly smooth surface for painting
Apply a guide coat. This is a very thin coat of dark paint, usually you would use an aerosol of dark blue for this. (Black takes longer to sand apparently)
Flat the guide coat back, this will reveal any imperfections you missed in the earlier stages. Repeat above steps until panel is perfect
Ready for painting!
the paint you want to be using is cellulose, i havnt try getting any yet, but i think its avalible at your local motor factors. there are other paints, but there harder to use/more expensive and deadly
hope that helps. if anyone has sprayed a car and know differently lettly know, cheers
