I would replace the pan. If it is not hitting anything the you may be okay, but this is going to effect a couple things. First it will affect the amount of oil the engine can hold. You will still be able to add the normal amount but it will push the oil level up in the pan and the crank shaft will potentially hit the oil which will aerate the oil and cause engine issues. Also, the oil pick up is submerged in the oil and you don't want to risk disrupting its ability to access oil.
As for the oil plug, you may be able to get away with just adding new oil and a filter this time and then change the pan (which will include a new plug) next time but clearly you are going to need to address this.
Sounds like someone severely shorted cut some repairs and did more damage in the process.
Let me know if you have other questions. Thanks
