I think as an introductory kayak, the one you pegged out is a great choice (good deal too). They have some at Costco at different times in the summer as well. I'm 5'11 and I have plenty of room in mine, but at 6'7 you may be a tad limited when choosing one so look for 10'+ ones; especially if you want to be comfortable. Mine was on sale for $199 at the end of the summer at a local outdoors store (reg. $399), but anything from $200-$500 should be good. Just make sure that the Kayak is closed since the leisure ones tend to be open and offer a less comfortable experience IMO (they are less expensive though). As for the paddles, ask the salesperson as you do not need high end stuff but you will want one that is solid yet lightweight.
I usually have a life jacket, rope and a whistle when I go out here in Quebec. I stick to calm water and bring my fishing rod from time to time; it's very relaxing. PS: You do not need any type of license to use your kayak but here in Quebec, you need a fishing permit should you want to fish.
Here is a list from MEC that can help you with basic regulations and below some extra info from Transport Canada:
