Is this a serious design or just to play with the chip ?
If it is for playing than it is cheaper to buy an eval board (see 
Olimex)
If it is serious, with 2 layer, you have very little chance to go 
through EMC aprovals. Check what is the difference in price between 2 
and 4 layer pcb and compare it to the value of your time.
(see other email for the rules of decoupling)
good luck
