I've been using Linux nearly exclusively since 1998. For someone with your background there should be nothing to it, at least once you have the system setup (Debian installers can be a bit finicky). OS internals are another story. Normal users, even developers, don't usually need to dive too deeply into those areas, but if you're interested there are plenty of resources available. I don't have a lot of suggestions for where to look but I learned a lot about Linux/Unix systems programming from the glibc info manuals as well as from the man pages. Beyond that it depends on your specific interests.
