One thing that will help us point you in the right direction is knowing how you're using it and what you're looking to accomplish. For example, I don't play bar gigs anymore and spend most of my time in the studio, so stuff like reamping and the occasional bit of MIDI are things I really enjoy.
Some folks don't gig and just want to plug in the guitar, turn on the amp, and rock out. So that's obviously a simpler scenario.
I tend to pick a profile I like and just use it, but there are also people who are really into sound design and will take a basic profile and sculpt it with EQ and other effects. Naturally there's more knobs to twist for that sort of thing.
Others use it primarily for gigging. They'll load up the profiles they want and perhaps use the remote and thus set up performances.
And then there are the people who actually create profiles. Not all of us do. For example, I really suck at dialing in a tone, always have. I love the fact that I can load a profile from someone who's good at it and just play guitar. Profiling is its own thing, so that's yet another use case.
There are also many varieties of studio rats (I'm the kind with the grey hair). If you're going to be recording, there are many things that can be a factor depending on the complexity or simplicity of your studio setup. Want to just jack the Kemper analog out into your audio interface and press the big red button? No problem. However, there's a wealth of options like SPDIF, monitoring, reamping etc. (I love the fact that the Kemper was designed with reamping in mind).
Many of us here are geeks, professional or otherwise, so the techie stuff comes more easily. For instance, I develop software for a living, so I guess technically I'm the variety of studio rat that has grey hair and a pocket protector. However, you don't have to be an auto mechanic (with apologies to Gary Larson) to figure this stuff out. It's the same as any product. If the tech manual has 1,000 pages it doesn't matter, as long as I know how to find the 3 pages that I care about.
So, what sort of scenarios are you going to be using the Kemper in? The more we know about what you're looking to accomplish, the easier it is to point you in the right direction.
I think once you get the basic concepts down you'll find it much easier to use than you might think. After that it's just a matter of knowing which page to look for to learn the particular new thing you want to do.
