Hey SuperCriollo!
I was looking at doing the same, only a few years in the future from now (school tuition takes precedence... -_-).
I was hoping actually to ask around to see if Badlands would be allowed as a tan uniform colour, but figured there wasn't any point to it at this time as I can't purchase any new gear right now anyways. If you're mainly a Canadian milsim player, ask the various organizers to see if they'd allow Badlands as a tan uniform (I think most will clear Greenzone as a green pattern, Badlands is kinda iffy).
Widowmaker Industries in Peterborough stocks the Rasputin stuff (which I've heard isn't bad as well) if you're looking local. I think the UR Tac Ops stuff will be better though (I'm saving up for these ones). You can also hit all of the rest of the items on your list at URTactical (they've got all the Pencott gear you'd need).
If you're running a PC, go for the combat shirt; it's lighter, closer fitting, and more breathable. The field jacket is okay, but I find you can overheat in those too fast.
Good luck, and pics of loadout once you're done assembling it! All that Pencott goodness
