Yes, all the ground wires can be grounded to one spot. Make sure that the ground is clean, corrosion free, tight, and that you get good metal to metal contact. Also make sure to use good quality ring connectors for the ends of the wires. The purple wires are for computer lines going to the Power-train Control Module (PCM) or more likely the Body Control Module (BCM). Other than that everything you have in the original post looks good. Please let us know how it turns out.
