Don't worry, I'll answer your questions.
FIRST ANSWER- If you are trying to get items through 'shop codes' (which have A's, B's, and C's), go to the shop, press the A button once, and then quickly press the A button 3 times. The shop keeper will look suprised, which means that you should enter in your password (with the left button being A, the middle button being B, and the right button being C).
If you are entering a password in that you probably got from Tamatown (or some other source), scroll down through the 'games' icon (which typically includes 'games', 'items', 'shop'... Until you reach 'Password'. After getting past the password shopkeeper by pressing B, enter in your password by scrolling through letters by pressing the A button, press the B button to select and move on to the next letter/number, and press the C button to go back if you made a mistake on a letter/number.
SECOND ANSWER- Those are non-Ura characters-- you have to get Oyajitchi to have a baby boy to get those characters.
