You need a decent pistol, so go ahead and get the CZ. You've already got .22's, so you're covered in that department already. Buy a 10/22 eventually, because they're just great rifles and fun to play with.
I also suggest that down the road you pick up a heavier caliber rifle or carbine. If you ever want to reach out and touch something, it's nice to have the capability.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen. ― Samuel Adams
