Whoa, first machine a 2 group lever?? Hardcore 8-) It is kind of a strange machine to start on the journey with, but hey, why not! Im sure you wont regret it.
The Lussos are wonderful machines, very forgiving and easy to work with for a lever group - they will also pull shots for hours without really overheating which is an annoyance for many other domestic lever machines.
You really do need to consider the grinder though in your budget, as the one you have may or not be suitable for espresso grinding.
