For the drum, there are different options to chose from (options from cheapest to most expensive) :
1- You can build it yourself
2- You can convert an acoustic drum to an electronic drum
3- You can buy an electronic drum
No matter which of the 3 option you choose, I'd suggest you to consult Megadrum's forum and another good address :

Also, if you choose to buy Syntex kit and convert an acoustic drum, you might wanna take a look at my thread (I've been asking a lot of newbie's question!!) :
