a) The criminal protective order does not cover as much ground as the DV protective order does, and it is usually a good idea to supplement the CPO with a DVRO.
b) His "stone hurling" would probably not affect the case too badly, although you don't say what "stones" you expect him to "hurl." The core issue is whether your reasons for asking for DVROs are true, not whether you might have a less-than-stellar reputation or record.
c) I cannot imagine a scenario whereby your losing a motion for a DVRO would be on your "record." What record are you worried about? Denial of a motion does not create any record beyond that: You requested and the court denied your request.

I agree with the attorney above. Also I would add that the standard of proof required for a DVTRO is pretty low, and I believe lower than that required for a CPO. Most people are surprised to find that DVTROs are usually granted on nothing more than the testimony of the person asking for protection. Further, a CPO is primary and any DVTRO is only supplemental, therefore if you have a CPO that lasts for as long as you think you need it and covers what you need, it might not be worth the effort to pursue a DVTRO as well. But CPOs don't usually last very long, and DVTROs can be ordered for as long as 5 years, so a good reason to pursue a DVTRO might be to ensure you will still be protected after the CPO expires if it is relatively short in duration.

I agree with both David and Sarah, and would further urge you to use these measures only when you need them. If you have legitimate fears and need protection, then by all means, seek that protection.
