Thank you very much. Which cards should I get first? I can´t afford to buy all the cards at once so i´ll have to do it spread out over a couple of months.
Thoughtseize. Its not as cheap as it ever has been, but Thoughtseize is still in standard and will almost assuredly get more and more expensive because it is Thoughtseize.
The land base will be annoying - Godless Shrine (at least 2, ideally 4) is pretty much required as you can fetch a B/W dual off of any black or white fetchland. Allied Color fetchlands are as cheap as they will ever be right now. Windswept Heath is sure to get more expensive in the future because Abzan colored decks are super popular in Modern. There is a wide-expectation that Battle For Zendikar will have the Enemy Colored Fetchlands, so I'd be leery of picking up Marsh Flats quite yet.
Sorin is like 10 bucks, but honestly, he's basically the reason you can ever beat several modern decks, so I'd consider him a relative priority. Still in Standard for another year, though, so no real pricing reason to rush it.
Lastly, Bitterblossom is not necessary at all and a lot of people don't run Bitterblossom. It is also $40 a piece. It also got reprinted starting today, but I don't expect it to really move much in price. I'd be very leery of picking up a set if you're just casually playing or trying to scrimp on costs.

C'mon awesome cards in the next two sets![/QUOTE]
I'd be a little surprised if Inquisition of Kozilek doesn't show up again.
