You don't need lubricant. If it is that tight but still leaks you probably have it cross threaded. It should screw on easily. If it needs lube, there is something wrong. Don't add any o-rings. If there wasn't one there before then don't add one.
For the compressor leak, the two o-rings are the only seal there is and the only one that is needed. You need to put refrigerant lube on the o-rings then tighten the bolt.
