However, in calibre, the 'Tags' column is very cluttered. What I would like is to have a few columns made up of just the tags that begin with one of these prefixes (or a custom column made up of only the tags in a particular user category).
Is this impossible? Is this insanely easy and I am completely missing something obvious?
Any help you can give me would be much appreciated!

It isn't clear what you want to do.
If you want to leave the items as tags but have subsets of them show up in another column as well, then
this thread might help. Note that doing it this way can be very complicated and can be slow if your library is large (10,000 books or so).
If you want to have a column per prefix, then use a text (probably not tags-like) custom column. I don't recommend this unless your categorization scheme is well developed and doesn't change.
If you want to have a subset of the tags in another column and have a hierarchy, then speakingtohe's solution is the best. Create a tags-like text custom column, then enter the items you want. Use a period instead of the colon, as in genre.xxx or fandom.yyy. To see the column as a hierarchy you must go to Preferences -> look & feel -> tag browser and enter the column lookup name in the "Categories with hierarchical items" box.
For a discussion of hierarchical items such as genre, see
Managing subgroups of books, for example “genre” in calibre's documentation.
I am not sure why you are putting series as a tag given that there is a series column, but that is another issue.
