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.

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 will if your hair is naturally curly, acquired traits (such as straightening your hair) will not effect your genetic traits (such as having naturally curly hair). If your were born with curly hair you will continue to grow curly hair, but you can always straighten the new grows if you want, but also try to embrace your curls.
it is impossible without straightening of some type
Hair straightening works by using heat to break down the hydrogen bonds in the hair shaft, allowing it to be reshaped into a straighter form. This process helps to temporarily alter the structure of curly or wavy hair, resulting in a sleek and smooth style.
