I'm using Rosetta Stone, Duolingo, and Memrise to learn Spanish. Is that overkill? I really want to be good at Spanish, maybe b1 level. B2 if I could, that would be awesome.

I also used Rosetta Stone, Duolingo and Memrise, so I don't think it's overkill. The resource that helped me the most with speaking and listening skills was Pimsleur. The other apps are better at teaching reading and writing skills.
No, it's not! As long as YOU don't feel too much pressure or stress, doing all those is completely fine! As for me, I take private Spanish lessons, use Memrise, and use Study.com, and, of course, Duolingo, which is not overkill for me. It is completely up to how YOU feel. Good luck reaching your goal! :)
The faster you get to some intermediate level of understanding/speaking, the faster you'll be able to consume Spanish medias. From podcasts, news and forums, to TV shows and such. This is really what you want your goal to be set to because your skills will skyrocket. The fact that you have the convictions to use so many apps at the same time is not only great, but really encouraging for your success. Keep at it, feel free to take some breaks in the long-term, but never quit !
