No one memorizes bolt sizes unless they see the same thing on the same engines over and over. We just grab a socket and try it to figure out if we have to find one that's bigger or smaller.
You didn't say what the problem is so how can we tell you how to prevent it from happening again? If you hit a large rock and put a hole in the pan, don't do that again! If you have a stamped steel pan that rusted out, that's a real common problem on Ford products, but normally we see that on trucks and rear-wheel-drive cars. Most front-wheel-drive engines used a cast aluminum pan. Those don't cause much problems. If the pan gasket is leaking, there's not much you can do to prevent that from happening again, especially with the miles you listed. The best you can do is to not over-tighten the new gasket, if there is one, because that can split it. If there is no gasket, just gasket sealer, be absolutely certain there's no hint of oil film on the mating surfaces. That will prevent most sealers from bonding and sealing.
