I totally agree on two points you make here. First being, they couldn't open the safes so they took them from the home. I think since they were friends with SS, they must have known there was $ in them, however, since they couldn't open them, they didn't know what the contents were exactly. Secondly, I agree with your interpretation of clothing. I think we may be taking "clothing" too literally. Yes, clothing could mean a t-shirt, but could also be referring to designer or sentimental items that were of value and warranted safe keeping. I am hoping we will have a better understanding of the timeline of the day SS was murders once LM has his hearing, because I am not 100% sold that LM went to the bank with SS. As I read in comments either here or on a news website, it's possible when LM called PT to say he was "at the bank" he was referring to being at SS home because he knew she had the $ in her home, thus assuming it was in one of the safes he took from the house.
