As always, it really depends. I don't know why you would want to straighten thick, curly, healthy hair when it is so beautiful and chic anyway.
It depends on how you have the straightening done. You need to find a professional on hair straightening if you want it, and be very careful when you do it at home. At home you should brush your hair 100 times after you get out of the shower and then use a straightener meant to turn wet hair straight. Then put in a very strong holding hairspray.
If you mean having a semi-permanent chemical straightening at the salon, you should wait at least 48 hours or longer. You can then go back to your regular washing schedule, and your straightened hair will last 3 or 4 months.
You can't get "rid" of curly hair! You are born with it. There are methods of straightening with a straitening iron or chemically. But chemically straightening your hair doesn't work well and does a great deal of damage.

If by straightening you mean with a flat iron then no, it won't cause your hair to lose curl.
straighteniners/ straightening serum and then majorly backcomb
Why would you want to do that? Straightening is to make curly hair straight; perming makes straight hair curly. Doing both in the same procedure would just destroy your hair. If you're trying to turn your tight curls into loose ones, having your hair relaxed is the way to go.
it is impossible without straightening of some type
A straightening shampoo is to help make the hair straighter, while a smoothing shampoo is to help make the hair smooth and not frizzy, and can be used straight, curly or wavy hair.
Japanese hair straightening is similar to perms but it just doesn't have as much chemicals and really expensive usually 200 dollars and up. It is mostly for people who have uncontrollably curly hair.
