When broadcast is off, then yes, mouse broadcasting doesn't happen. This is usually a good thing because your camera views are different, so you only really want it for 2d things, like menus and similar, except for the odd occasion.
If you really want mouse broadcasting and not keyboard, then in the Always On keymap you can set a hotkey on the Activate Mouse Repeat mapped key.
For Master/Slave movement operations I tend to create mapped keys on CTRL+W, CTRL+A, CTRL+S, CTRL+D, CTRL+SPACE to send to the standard WASD, SPACE to the other characters. You can do this easily with a Key Remap in the Mapped Key Wizard.
The rest of the config about who uses which keys, or whether you have all the toons using the keys but pushing different rotations is up to you. Frankly it is boring trying to configure each character so they do the right thing when I broadcast the 1 key, I'd much rather press the 1 key and have all the toons do all the right action in the rotation they were cycling. Or I press the 2 key and they run a different rotation (well, some might continue on the previous rotation, but maybe the healers kick in with the heals rather than addition DPS). I do stretch a little here because I use a G13, so the key I press is actually G13-G13 or G13-G6, but you get the idea (hopefully).
As for JAMBA, ISBoxer has a mapped key in Always On, called JambaMaster. This is executed on character switch. This is designed to tell JAMBA who the current Main character is, so when you switch to another toon, the slaves all follow the new main, i.e. the character you have switched too. Most people like this feature, so the characters follow the toon your driving rather than a different toon. You can disable it in JAMBA, or you can remove the Mapped Key on switch which is set to execute on each Slot in a character set. As for your config issues, this might be that ISboxer uses different WTF files for each character, but as other people don't have this issue, I can only guess that something is incorrect in your install, whether something in the file paths, multiple WOW installs or something else. Unfortunately this is not the JAMBA helpdesk, and I am not immensely familiar with it, although someone else may have some ideas, but there is usually good help in the WOW Addon forum on dual-boxing.com.
