A few questions, iClimb.
What peaks have you done in winter around here?
And what was that mixed alpine climb?
There are lots of ways to do Mount Washington in winter. Are you planning to do some ice climbing via one of the gulleys in Huntington or go up via Lions Head or another trail?
Ed has lots of good advice above, especially about instruction. I concur with the wilderness first aid course (I need to redo mine).
I think you've had some instruction already, but even so, there's always more to learn.
I recommend two things off the bat:
1. an avalanche course -- I recommend Marc Chauvin in New Hampshire: http://www.chauvinguides.com/ (this is really important)
2. more instruction in winter snow/ice travel/climbing. I'm not sure if this is something you've already done, but I recommend hiring a good guide and doing a mountaineering course that includes ice climbing. If you pick a good guide and he/she knows you want to learn, not simply be led, you can pick up a lot of info and they can teach you what you need to know.
Also in New Hampshire, I've gone with Mark Synnott: http://www.newhampshireclimbing.com/

Obviously, if you've already done this type of course, above, you'd pick something harder. Or you could talk to the guide about what you've done and what you want to learn next and come up with something custom.
I think your attitude of getting out there and doing it is important, as well as your openness to learning. Guides and courses do cost money, but if you pick the right guide for the right info you can gain a lot during that experience.
I have just a little bit of big mountain experience, but am working on filling in my own gaps of knowledge and experience and will continue learning more too, like taking more in-depth avy courses, more alpine training, etc.
I'll leave you with another question. What do you ultimately want to climb?
Good luck. Keep us posted.
