So let's start by getting your data in the correct locations. Then we'll set up the views.
There are some fast means to move data from one field to another. The Library Tools > Move / Copy Fields tool is easy for copying or moving data from one field to another. You might use this to select some tracks, and move, say, Oscar Peterson from the Artist to another field. I use a custom user field called Featuring for this.
To create a field, Tools > Options > Library & Folders > Manage Library Fields. Click the Add New Field button, and give it a name. Select the Data Type as List. You can click the Default search field checkbox too.
Now, use the Move / Copy Fields tool to copy your Artist values, where necessary, to Featuring.
And now be sure your Artist fields are correct (or Album Artist, for multi-artist discs).
Now, let's work on Keywords. Add the necessary keywords to the Keywords field for an album. For example, add Remastered; Bonus Tracks to add these two keywords. Alternatively, you can add them to a new field that you create. You might want to use some other field of either a list type or a simple string. A list gives you flexibility of being able to check the relevant items for an album, such as Remastered, Bonus Tracks, SACD, etc. all while keeping the items consistent across albums. Or you might just want an exact string, such as "Remastered with Bonus Tracks". Its up to you. Maybe you want to make this field only available for Audio, and might call it Album Variant as we discussed above.
Once that's done, you can remove the now redundant portions from Album. There are programmatic ways to do this, but for now, do a few to get the idea.
You can use the Tag Action Window or the file list with the appropriate columns to view your work. Add fields or columns to either, respectively.
Get that going, and we'll go to the next step. Its really quite fast once you get the hang of it. Work on 1 or 2 albums to start; then move onto larger selections or your entire library. Remember, Undo can save you if you make a mistake.
