I doubt that any of those features were changed in the new version.
I don't have the new version installed but here is how you do them in the version before the latest:
Presets, in the Develop module, left side of screen, click the "+" by the presets dropdown.
There should be an 'import presets' option.
Deleting files, mark each file you want to delete with the 'x', when you have them all marked, do a control-backspace
and select 'delete from disc'.
Don't import duplicates: in the import module there is c check box for that.

I think these guys have what you are looking for if you want wet process digital prints on a small selection of paper.

However, you can get better results with pigment inkjet and baryta paper. You may want to try these guys for that:

As far as fading and ink running, this is no longer a problem. I either have the print laminated or sprayed with a coating at the print lab, or when I print at home I will use one of the roll-on Breathing Color coatings, like Timeless Print Varnish, certified 100+ year archival by the Fine Art Trade Guild. Is 100 yrs enough for you?
