Hi Grampswyatt and welcome to the forums. Palomino gave some good advice. The Torii should drive most efficient speakers (94dB+) fairly loud in your room and the SE34I.3 would do good as well (but with even more efficient speakers 97dB+). With low wattage tube amps you are best to stick with very efficient speakers ... the lower the wattage, the more efficient your speakers need to be in order to give you more headroom for volume.
What I've come to understand from people who have compared the Rachel SE34I.3 and the Super Zen SE84CKC that they are somewhat close in loudness even though the Rachel as a few more watts than the Super Zen, but the Torii will drive less efficient speakers to higher volumes. So that gives you a few options ... if you want all the S.E.T. sexiness stick with the Super Zen or Rachel, but if you feel you may want the headroom to experiement with less efficient speaker designs than the Torii would be your best bet.
If it were me, I wouldn't put too much effort into CD playback ... a PC or MAC combined with a good DAC will match (and can even best) all but some of the best CD players out right now ... I think you would have to spend quite a few thousand $$$ to get a better sound out of a CD player compared to a computer with a good DAC. If you have a lot of CD's, what I would do is Rip them to the hard drive of your computer and focus on the playback ease and great sound you can get from a DAC/PC combo and forget the CD player all together.
Ok, since the Rachel, Super Zen and Torii are integrated amps (the Rachel can be ordered as an integrated option) there is no need for a PreAmp (although there has been a lot of discussion that it can improve the dynamics of your system, but even still it is not necessary with those amps and can always be added later if you want to experiment).
The Super Zen comes with 2 inputs and the Rachel can be ordered with 2 inputs as well, so you have inputs for 2 sources (1) PC/DAC and (2) Turntable/Phono Preamp and you would be all set, however if more inputs are needed you can add a Switchbox to cover the rest otherwise you will have to switch cables back and forth between your sources.
If you want to listen to vinyl records then you need a turntable of (course

), but you will also need a phono preamp as none of the Decware Integrated Amps have a phono stage/preamp built into them. There are a lot of good ones out there depending on your budget, but I have heard amazing things about the Decware ZP3 Phono Preamp.
If you listed a budget we could help you get close to it, but the following setup would be a really good system.
1. Decware Super Zen SE84CKC or Rachel SE34I.3 Integrated Amplfier.
2. Decware ZP3 Phono Preamp (or an entry level phono preamp such as the Rega Fono MM or MC).
3. Rega RP3 or RP6 Turntable (or VPI makes great tables if you want to spend a little more).
4. Schitt Gungnir or Bifrost DAC (combined with your PC).
5. Speakers ... are pretty subjective, but if you like horns Klipsch's are really efficient, also Zu Audio, Tekton, Omega, Hoyt-Bedford and Blumenstein Audio make really efficient designs.
6. Speaker and Interconnect Cables and Misc.
If you wanted to improve the sound of your sources - you can add things like the ZBOX later and then experiment with Power Conditioning, Power/Interconnet/Speakers Cables, etc. but I would get a basic system setup first.
Anyways, that's my .02 ... enjoy your journey!
