Try visiting arrl.org for study materials and so forth. There's tons of PC programs including various free ones, for morse code practice. Nobody uses morse code on 2 meters (at least the part of the 2 meter band where those handhelds operate) though. Even on the low bands, digital modes like PSK31 make morse code obsolete, though some traditionalists still use morse.

I really wish someone would make a complete, portable, 20 meter psk31 transceiver in a box. It would have the radio, keyboard, display, batteries, etc. all in one unit, rather than make you plug all kinds of computers and junk together. It would look like one of those ruggedized palmtop computers like the UPS guys carry, but maybe the size of a hardcover book, weighing a couple pounds. It would be a great backup or alternative to a satellite phone.
