1) Best Paint:
Use auto paints. the spray paints such as DupliColor. Use the same brand of primer as the paint for best results. Do a lot of thin coats not one heavy coat. Sand your laptop till it has a flat/smooth surface then start painting with many coats. Follow the instructions on the paint can.

2) Decals or Paint:
Your choice really. I would suggest paint though.

3) Protecting the mod:
No, not needed. Just paint properly with many thin coats and use primer to finish, and you will get a nice shin reflective look.

Notes:
Painting requires some basic skill although i think you can do it yourself. 2 ways to paint a laptop:
i) Take the laptop apart, take the casing and spray paint the whole thing.
Pro: this will paint your whole laptop and allow for easier working.
Con: WILL void your warranty most likely, and can be a bit tricky.

ii) Taping and Spraying small sections. Tape parts such as the fan holes, speakers, ports, etc so that the paint does not get inside your laptop and then start painting.
Pro: Easy if doing small areas such as only the top of the laptop, will NOT void your warranty
Con: Hard if doing the whole laptop (almost impossible

Suggestions:
Use "i" if your warranty is finished or you don't care and just want to make it look better.
Use "ii" if you want your warranty and just want to do small areas such as the top of the lid only.
Use decals if you want to do really small areas.
If your laptop is really old and out of warranty, use "i" to paint it then, top it of with some nice professional looking decals.
If using "i" my suggestion is to paint the whole laptop 1 color and make it as shiny as possible like a brand new car and then use some matching decals.
If using "ii" make sure you cover all your entries into the inside of the laptop carefully- spray paint fumes still carry a lot of paint in them and this is probably not covered by any warranty.

Research:
Research on painting techniques (search on Google/NotebookReview). Get detailed guides on how to achieve the "new car shine" look on your laptop.

Price:
Painting only: $20-$70
Decals only: $35-$90
Painting+small decals: $55-$160

 

A lot of people here vouch for rattle can krylon fusion. it's a plastic specific spray paint that produces pretty good results. you'll get plenty of response from people. syndrome specifically knows quite a bit about painting and he'll comment here soon enough so ill spare you the details

 

i personally prefer duplicolor and auto paints because i like the shinny stuff

 

No. Primer is the BASE coat. It's what makes a nice surface for the paint to adhere to. Sand the parts you want to paint with a high-grit sandpaper, then apply the primer as evenly as possible, possibly multiple coats, then you want your color coat(s), and then on top you want what's called a clear-coat.

What you want to do in that case is disassemble the laptop completely, then put the tape on the INSIDE of the grates and holes and such. Don't paint it so thick you block airflow. You don't want to paint the laptop with sprays if it's assembled, unless you're a very good airbrush artist or only want paint on certain parts. A full color change requires full disassembly.
