Ok thanks all. So let me make sure I understand what you're saying. Since I have a 600ex-rt (which is radio), I should make everything work with that.
Maybe, maybe not. The RT system has the most features, though, so it may be worth it, if those are features you need. And it's kind of a "waste" of the 600EX-RT not to use the system.
So get the YN-E3-RT to fire the signal (on hot shoe) and my 600 will receive, get another YN 600 (since its cheap and radio). Since they are radio, I don't need line of sight and no receivers since they are builtin to the flash. If I want my old flashes to work, I either just flip it to optical (for YN) or get the YNE3-RX to make it receive the radio transmit (430). And all of that will render my 603C IIs useless. Correct? In this configuration, can I remotely control the power of the flashes?
You'll be able to remotely control the power of the TTL-capable flashes, but not your YN-560s. You'd basically have to swap your YN-560s for YN-600EX-RTs, and your RF603s for the E3-RT/RX units. This is the main problem with going Yongnuo. Their three triggering systems (RT, 622, and 560/60x) do not interoperate and are incompatible. You'd have to stack triggers to get the systems to work together.
[Note: there's also the Phottix Laso transmitter and receivers instead of the Yongnuo RT ones. But same problem. Laso and Odins won't work together. But Odin and Stratto (their version of the 60x triggers) will).
So when would you use the 560TX or the 622? For non-radio, older master/slave configurations? Is that called infrared?
The 560TX and 622s are both radio systems, not optical. Canon's pre-RT wireless system is optical, at near-infrared frequencies, but it's still visible light--kinda like using a TV remote. That's what the EX on Yongnuo flashes indicates--that it can be used as a slave in Canon's optical wireless system. RT is a newer radio-based system with some new feature: 5 groups instead of 3, ID codes for unique channels, Groups mode, etc.
You'd use the 560-TX on-camera as a master if all your remote flashes have RF-602/3/5 triggers, or are YN-560III/IVs. With the YN-560III/IV, the 560-TX gives you remote power/zoom control, but no eTTL or HSS, and no remote power/zoom control over your TTL flashes (600EX-RT, 430EX II).
With the 622 system--which you could also use, but then you can't use the built-in RF system in your 600EX-RT, you'd have a 622-TX on the camera, and with either 622 transceivers on a TTL flash, or the built-in receiver in the YN-685, you could have remote power/zoom control, as well as TTL and HSS. But. The YN-560s are manual-only flashes, so in the 622 system, the 560s have no remote power/zoom control. Mutually exclusive systems.
And if you throw in Paul Buff lights, like Alien Bees, digital Bees, or an Einstein, the picture gets even more complex. Because PCB lights can only have their power remotely controlled via Cybersync triggers (although I think the Einstein can be controlled by TTL PocketWizards), and Cybersyncs don't power control speedlights. So, you'll probably have to stack triggers.
If you're really looking at future expansion, you may want to consider moving to Godox or Phottix, instead of using Yongnuo. But this will probably require ditching the YN-560/603 gear, not using the RT system, and/or getting used to using the 560s without remote power control.
In the Godox system, the new X1 triggers are TTL/HSS, so you can at least use them like 622s to integrate your 600EX-RT and 430EXII. But. You can also grab some TT600s instead of YN-560s. The Godox TT600 is the same price and and has a feature set equivalent to that of a YN-560IV, except its builtin transceiver works in the X1 system. You'd have remote power control over the TT600 in the system if all you want is a super-cheap manual speedlight. You also have a TTL/HSS choice (TT-685), or manual/TTL speedlights that use Lithium ion battery packs instead of AAs (Ving V850II, V860 II), all of which have X1 triggering built in. Godox also offers barebulb flashes and studio strobes with X1 triggering built-in. (See: http://flashhavoc.com/godox-flash-system-overview/).
And they currently have X1 transmitters in Canon, Nikon, and Sony flavors, and plans to add Pentax, Fuji X, and Four-Thirds to the list. The system isn't perfect. It's going through v1.0 teething issues (lots of firmware updates), the transmitter units probably aren't final, and the studio strobes are much more expensive than AlienBees, since they offer TTL/HSS. But this is a complete system.
Phottix is building something similar around their Odin/Strato triggers, and are even getting buy in from other manufacturers like Sekonic and LumoPro. But if you like Yongnuo pricetags, Godox might be closer to what you want. The main problem with buying Godox is that they're kind of like the Samyang of lighting gear--they get rebranded a lot.
