Seems a certain to merge those. Merge Rebekka into Rebekka Karijord. Always merge to the better quality target. When looking at Rebekka that one release is clearly part of Rebekka Karijord’s catalogue as seen on Wikipedia. It is her first release.
When merging artists you get a question about “Update matching artist and relationship credits to use the target artist’s name”. In this case you will not rename as “Rebekka” should be used as an alias here as that is what she used on that album. So leave that box unticked.
With scripts - there are better threads buried in the forum. Certainly make sure you get some of @jesus2099 works in there. Super Mind Control Turbo and INLINE Stuff are little goldmine of goodies
And the best of the lot - assuming you have decent broadband lets get that ARTWORK visible
A better thread on favourite scripts: Your favourite User Scripts for MusicBrainz?! (so that they can be used while redesigning!)
This is why I scan the booklets in full and upload them here at MB. It means I have the booklet ready to read on screen without digging the CD out of storage. By uploading it here at MB I do the double task of having an Internet based backup that will download via Picard. And more importantly - I am sharing with the community.
