You should definitely give the ones that are currently there a listen. Worth your time (just make sure to skip ahead when they say spoilers). I particularly like their examples of some of the mechanics, it is a good companion to the book when you are learning the different classes.
As far as other podcasts, the Iron Tavern podcast is an actual play podcast. I'm not a huge fan compared to other actual play podcasts with other systems, but it is there. I'd listen and form your own opinion.
As far as tools, Purple Sorcerer Games (http://purplesorcerer.com/
) has an app (IOS and Android) that has a dice roller/rules quick references (all blessed by Goodman Games), plus a broad selection of other tools on their website. Give them a look.
Have to have adventures. Hm... I suggest you create a different post and solicit more opinions than just mine. I'd start with the highly rated Goodman Games ones and then start branching out. What kind of fiction/setting/style you like? Lots of DCC material (created by Goodman or through 3rd parties) is varied.
Want to play off planet and fight aliens? There's an adventure for that. Want to go trans-dimensional and face off with gods and patrons? There's an adventure for that. Want to go Scooby Doo and hang around a haunted mansion/vineyard? There are modules for that. Want to play through megadungeons that were created for other systems? There are books for that. Want to trek across the Appalachian mountains and explore folklore unique to that region? There's an adventure for that.
Are you running games as a judge or are you a player? Don't read the stuff if you are a player. It is best to walk through it in character during a game. If you are the judge, depending on your budget, read as much as you can.
I'd start with those in the core rulebook and read over the free Google+ modules to get yourself started for free.
Then, here is a comprehensive list by Raven Crowking, a tireless individual that writes some blog posts about DCC:http://ravencrowking.blogspot.ca/2015/0 ... -list.html
This has all of the modules created by everyone listed.
And here is the first post in a multi-post series on his recommendations:http://ravencrowking.blogspot.com/2014/ ... art-i.html
Good luck to you, and I hope you post this topic on a unique post. Try to explain your preferences when you post, it will be better than just asking for our own opinions.
