I've been vaping for one month tomorrow and will not bother to state specifically how much time I've spent researching, money I've spent getting started, or time spent trying this or that or the other thing... even being a retired Submariner, Navy Chief and a gadget freak to boot -- that is to say, not one to shy away from inherent complexity -- it has been VERY surprising how difficult it's been to get good, solid information and hardware to get started. So I've felt this pain, but one of the ones likely to push past it to get to the goal.
I think you're absolutely right. It's a flipping mess out there with lots of options, almost too much information to make a good decision on your first steps, lots of matters of taste and technique, and it's way too easy for a bad initial purchase to snowball into an (initially) expensive and frustrating experience.
While I haven't really had any physical craving for cigarettes, I have dang well missed the simplicity of a box of smokes and a lighter!
Designers and Engineers, e-Cig / PV manufacturers, take note: that is your "UI" standard. A pack of smokes and a lighter. The first one of you that creates a system as simple to use as that, with extremely easy, well-documented use and maintenance, at no more than the long-term cost, and with the option of all the wonderful juice flavors out there, could not only rake in but also keep the "former smokers/ new vapers" market and make a mint.
(Hard core enthusiasts, I have nothing against you and do not fret; as with any endeavor, there will always be room for your plan to turn that space heater into the world's most awesome whole-house PV... it's just not for all of us. Peace.

)
All of that said, despite the early frustration and sometimes overly complex setup/operation/maintenance of today's eCigs/PVs, I must tell you Chris... it's worth it. It's worth the effort. Really, it is.
It's worth it to me to wake up without my mouth tasting like sulfur. It's worth it to me every time my wife kisses me without hesitating, without wrinkling her nose and muttering "phew!" under her breath. It's worth it to me for the better sleep I get since I no longer stop breathing from time to time at night... that I don't have to make sure that I have a pack of gum or mints with me all the time... my hands actually feel I warm again... don't have to worry about making sure to stay down-wind of others when I "light up"... for the fact that I no longer get a runner's high from two flights of stairs.
Take a deep breath and accept that, for now, going from Smoking to Vaping is lot like going from any "casual" activity to becoming a hobbyist. While this isn't a perfect analogy, making any casual activity (smoking) into a hobby (vaping) almost always involves taking the time to learn more about what you're doing, some cost as you acquire more materials or items, some frustration as you learn the things that do and don't work well for you, and certainly more time as one learns more about it and hones the skills needed to partake in it.
The big difference in our case is that our casual activity was killing us. Our new hobby will not.
Unless, perhaps, you really get to the point of wanting to build that whole-house PV... no good can come of that. Just sayin'.
Being well beyond the point of TL

NR, the last thing I'll recommend is that if the Internet is a big bottleneck for you, try spending part of a day using one at the local library, or if you have a laptop spend a while at a coffee shop or some place with free Wi-fi, and see if you can't dig up more if the info you need to get where you need to be.
I wish you EVERY success in going the distance and sticking with it!
