The general advice is to rent or get whatever you can find in you size second-hand and invest the savings in lessons.
Also, it is entirely possible that as you become more experienced and progress in your riding that your focus/style changes - you might discover that you prefer big mountain/backcountry riding over park, etc.

Again, I do not want to come across as discouraging (cool that you are getting into snowboarding!), but gear should be one of your last considerations.

One exception to the above: Get well fitting boots! From a store (preferably a proper board/ski store), not from a mass retailer let alone online. Proper fitting boots are hands down the single most important piece of equipment that you can get. Next are padding and safety gear plus a decent jacket and pair of pants (you might have something usable from your skiing days already).
Everything else can come (much) later.
