When you say "CA 50", do you mean Cyanuric Acid, stabillizer, conditioner, CYA (all synonymous)? If so, your conditioner (CYA) level is fine for most pools. Keep it there for awhile, if you find you have to add chlorine more too often, then consider bringing it up.
As far as clarifier (not the same as stabilizer), few pools need it. Is your water clear? If it is, you don't need clarifier and if it's not, you probably don't need clarifier.
How do you chlorinate the pool? Bleach?
Your numbers look good to me. If your pool looks good, then; congrats! Keep the FC between 3ppm and 6ppm (stay near the high side and never let it go below 3ppm).
