new to signed applets......need help

Hi...I'm new to signed applets and I have some questions, that several tutorials i read did not really answer..

1) When doing keytool -genkey....

what are each of these used for

-alias

-keystore

-storepass

-keypass.......I the tutorials seem to be confusing what each of these are actually used for...

2) How do I create my certificate....

one tutorial said to use the -extport argument and and other said to use -selfcert.....? what are the differences between each of these?

3) If I wanted to distribute the applet to many people...some told me that I can obtain a certificate from a trusted source?.....I would I use the certificate to signed my applet then?
