30 is about the level it takes to complete first play-thru, so make sure you have chosen true vault hunter mode when you load up for your second play-thru otherwise lvl 30 stuff is all your gonna get. As for the slots, the bad ass crater bar being DLC, was not out yet when the editor was made, just for the vanilla so just sanctuary works.
Best thing to do is just activate the unlimited gold keys for the chest in sanctuary as that will dish out weapons that will always be scaled to your level.
The Editor runs smooth good. Every stat is editable. Yes, the Windows Defender yells there is a trojan, but you can set the Defender not to scan the temp folder, and then everything is good! 😉
:edit: Uhm, sorry for the double post, i've seen it 2 posts above me... 🤔

If you do not want to risk the whole temp folder being excluded, the game uses this file here if I remember correctly.
Just add that to exclusion list.
