Reply to advice for gears

i'm a newcomer in this job,and I used to be a mouse oriented DJ (you know what I'm talking about),also I don't want to upgrade my gears so often so I'm believeing of TP2,2xCDJ-2000nexus,DJM-900nexus,2xF1(to control the Remix Decks),1x Kontrol X1,and a notebook.

Anybody suggests another kind of setup?and somebody believes the best notebook to handle them up?

N.B.:I will use the CDJ in HID
