Well you can do alot with $2000. The parts that you buy for the EX wont be universal over to the LSVTEC. So i would just say, get a cam sprocket and pulleys for now and save the rest for later and when you do the swap you will be able to sell some of that stuff to get some of your money back.
P.S. The engine code on the 96-00 Civic EX is D16Y8.
