Send them all to yourself to one address. To avoid the fee, use a hacked up client with fees removed, but it may take a while for the first confirmation.
I highly recommend creating the "hacked client" yourself by downloading bitcoin-qt yourself. In the src folder edit main.h and change both to zero
static const int64 MIN_TX_FEE = 50000;
static const int64 MIN_RELAY_TX_FEE = 10000;
compile with the makefile and save it.
and make sure you send more than .1 btc or it's possible the transaction will never confirm.
