Rogues Memorabilia
Out in 2011, this hand-painted lead figurine was made by Eaglemoss.  They’re a UK company which released figurines along with a magazine about each character.  Their general DC line is over now, but they’re still making lines of chess figures which are basically identical to these ones.
Professor Zoom here is about 3.5 inches tall and comes with the lightning rod from Flash: Rebirth (the cover of his magazine also uses art from the series).  Eaglemoss figures are nice solid statuettes.

This 2013 book lists all the hero and villain pets in the DC Super-Pets universe.  Many appear in the Super-Pets series of books, but I don’t think all of them do — for instance, Captains Cold and Boomerang and their pets have entries in this encyclopedia, but as far as I know they haven’t yet appeared in any books.  Professor Zoom and his newts appear in their own book, however, as do Gorilla Grodd and his pet monkey.
The art is absolutely fun and adorable, and the creators clearly had fun inventing all these pets.  It’s very kid-friendly and overall quite cute, and still readily available for sale.
(You can see the entries for the Rogues and their pets here.)

DC Super-Pets: Salamander Smackdown is a children’s book published in 2011 by Capstone.  It’s about the speedster turtle Whatzit battling two evil cyborg newts, but the newts idolize Professor Zoom and eventually become pets for his nephew.  It’s mostly text, with some illustrations by Tiny Titans creator Art Baltazar.

This convention-exclusive figure was only available at the 2011 San Diego Comic-Con.  As suggested by the figures in the background, it represents Professor Zoom in the Flashpoint storyline (and not Zoom, as the text claims).  The figure is about six inches tall and comes in some surprisingly elaborate packaging.
The figure is a bit unusual because it has an entirely new head sculpt.  Many convention exclusives are typically just repaints of other toys for reasons of cost, but there was actually a bit of extra effort put into this figure.  And his expression is so deliciously evil.

This card (it’s a single card, showing both sides) is from the 1994 DC Masters series by Skybox.

The card is foil-etched, a double-sided “spectra” which is a rare chase card (in other words, difficult to find).  One side features the Flash, and the other depicts Professor Zoom.  The illustrations were painted by well-known fantasy artist Boris Vallejo.

These two cards (showing the front and back) are from the 2007 DC Legacy set by Rittenhouse.  The cards show the characters’ early Silver Age selves and also their modern look, but although the Reverse-Flash card says it’s Eobard Thawne, the modern image actually depicts Zoom.

This set also had randomly packed hand-drawn sketchcards included, and I’ve seen some Captain Colds and Professor Zooms.  But they’re not officially counted on checklists, and I don’t know how many there ever were.

These cards are from a game called Top Trumps, which is apparently popular in Europe (it seems to be rare to non-existent in North America).  There are actually a whole bunch of Top Trumps sets, based around varied themes such as characters from TV shows and movies, British celebrities, teen bands, various animals, and dinosaurs.  The cards have different stats, and the card/player with the best stats wins.
The DC version of the game was first released in 2005, and includes Captain Cold and Professor Zoom.  There was another set without Rogues in 2006, and a re-release without Rogues a few years after that.
This is literally the only image I’ve ever been able to find of these cards; I don’t have a set of my own.

Out in 2012, this is volume two in a series of RPG sourcebooks.  It contains alphabetized biographies and gaming stats for a variety of DC characters, including quite a few Rogues.  
Some Rogues have shorter entries than others; the bios/stats for the Top and newer Rogues like Tar Pit and Girder are abbreviated and contained under the entry “The Rogues” rather than in their alphabetical position.  James Jesse is mentioned in Axel Walker’s entry, but doesn’t get any stats or much of a write-up.  The two Mirror Masters share an entry and each gets a biography, but seem to share stats.
The books are published by the gaming company Green Ronin.

The 1977 DC calendar doesn’t have a lot of Rogues content, but Abra Kadabra appears on the cover and there’s a bit of Grodd and the Rogues as part of the September pin-up.

Also from 2012’s Action League Flashpoint line, this fellow is supposed to be Professor Zoom but looks more like Zoom (I wish toy companies et al would get it straight).  With his fist raised, he’s about 3 inches tall, although his head is pretty much at 2.5 inches.
This also comes in a two-pack with the Flash, although fortunately a different-looking Flash from the Citizen Cold pack.  And can also probably still be found at retail.
