Blackmirror- They're not BSing you, it really is all a matter of practice. The only "trick" is that you gotta practice doing the right thing.
You oughta get a book about this stuff. Explaining it is tricky, especially stuff like learning to match the revs/double clutch. It's best to learn this stuff from a good instructor, but you *can* learn it from a book (I did). Maybe Bondurant's book, available from Motorbooks International. Really is worth the money.
I'm with MS22- I too would avoid the e-brake thing, you don't need to do that and it will just delay your acquiring the skills you need.
Definitely practice on flat ground so you get the basics down. Doing it on inclines is just a matter of doing it faster (foot moving from brake to gas) and with greater control (tougher to get the "stall vs. bucking" thing right). Doing it under easy conditions (flat ground) will help you get a feel for what's going on. Try to *feel* the instant the clutch engages, feel how the little bit of gas you give it makes it all happen smoothly. It's all about being smooth.
Generla Lee- Yeah, *some* cars are pretty much foolproof and will let you engage the clutch with little or no gas, but I've only driven a few cars like that and I've only owned *two* of them that I can recall. And I've driven and owned a *lot* of different cars.
MS22- Heh heh, yeah, I too was basically told to "drive it and don't mess it up" with no real instruction

Cars with light flywheels can be a royal pain to drive smoothly, let alone to learn with.
Project "2"- Heh heh, hope we dont scare Blackmirror off with talk of such stuff

Yeah, it's only when you start doing things like heel & toe that you really take advantage of a manual's advantages.
I wouldn't rev match though, except maybe at first when still leaning. Or maybe on a track when things are happening fast, but most of the time (and always on the street) I'll double-clutch to save the synchros. Too many used manuals have worn out 2nd gear synchros, and double-clutching is becoming a lost art

Heel & toe double clutching is *driving*
Heh heh, I know some old-timers who think that having to double-clutch *up* shifts is no big deal
