OK, here is how I do it. I'm a Mac user. I have a mother folder named PHOTOS. I make subfolders in it labeled with each event, photoshoot, etc.. The PHOTOS folders sits on my desktop. So does another important folder named CAPTURES. This is were I transfer the jpeg folders from the camera, renaming them in the process. For example my NEX6 folders start with 100MNex6 and I'm now up to 135MNex6 (the M got forgotten in the beginning, so I left it there).
After a camera folder is added to the CAPTURES folder, I open it in Photoshop (I use a very old version, CS2, which has a pretty convenient browser). It offers thumbnails, that appear in a decently sized window to the left when I click on one miniature. This way I can see what pictures I want to PP. I basically resize (20x30 cm at 240 dpi for printing, then 72 dpi for websharing, email, smartphone, etc). I usually fine tune WB, contrast, and add a tad of selective sharpening (or softening) if needed). If I need vignette added, a back and white conversion or a frame (or all three of the above), I open the resized and renamed picture in Snapseed, do what's need, and resave it there. My typical naming scheme involves the direct nature of the subject, as well as a hint of the date. For examle, all my daugter's pictures are named : MarlaMonthYear-unit, as in MarlaDec12-01, 02, etc. Vacation pictures will sound like Vermont2012-01, 02, etc...
I've used this naming scheme for a couple of years now, and it makes it very easy to locate and find any given picture.
Regarding deletion, I delete an awful lot in-camera. Then the obvious trash when browsing the shots in PS. All the remaining shots are kept. After 2 or 3 months I move the original capture folders to an external drive.
That's it !
