By the sounds of it you need to do a lot of you tube video watching
But seriously, go talk to the guys in your local paint supply store regarding the paint types etc., most I've ever dealt with have been very helpful.
A by no means exhaustive list of what you'll need, this is assuming you've got the base body work ok in terms of filler work etc.
Equipment:
Compressor (capable of at least 12cfm I'd say) with some 3/8 hose
A good quality spray gun
Disposable coveralls and gloves (screwfix)
Disposable mask that allow you to spray 2K (2 pack) paints (I use these -

DA sander/polisher - you can do it by hand, but my god is it soul destroying! Might want an air palm one for sanding, such as
link and then an electric polisher e.g. h
linkMasking sheet and tape - more than you'd imagine!
Paint: I find these guys very good
www.clostermann.co.uk/Barrier coat - if you have funky old paint, especially celulose on the car, I strongly advise a barrier coat first to make sure you don't get paint reactions. The high build primer can do this if you apply a lot of thin coats. Otherwise bare metal the car, but this takes time!
Etch primer (for bare metal) -
linkHigh build primer - I find 2K the best by far
linkPaint -
linkThinners (I like to use fast, since I don't have an oven to cure it in!) -
linkHardner -
linkSundries:
Wet and Dry paper/sanding pads - various grades to suit each part of the job (say 600/800 on primer, 800/1200 if you sand between colour coats etc.
Take cloths - to remove dust prior to each coat
Gun cleaner/general thinners - to keep your gun clean
Paint filters - I find it a good idea to sieve paint into the gun for colour coats, just in case you get any bits in during mixing, nothing worse than a clogged gun or bits in your fresh paint!)
Panel wipe - very important - you must make sure everything is free of grease/silicone etc before paint, otherwise life will be hell....
Cutting compound - used for getting the paint to a pretty good shine, then take over with your preferred polishes/waxes etc.
I'm not going to go through the processes - google will tell you all, and youtube videos can be very helpful. But if you are starting from zero equipment wise, the whole job is going to cost in excess of a grand to do well - the required quality of compressor will be £300-400 second hand on it's own for example.
My words of warning are that unless you see a use for this stuff after the job, or are planning on selling on, be aware you will very quickly get close to the cost of a cheaper respray by someone else, and that's without factoring in a week of your time (I tend to book a week off work to do a full respray to a good standard). Plus if it goes wrong you would not believe how frustrating it can be!
Good Luck
