Hi,
I'm not sure why you would leave it connected. It won't be plugged into power. Also, you don't want to risk one of the connectors shorting. I wouldn't recommend it.
As far as the alternator, it really isn't too hard of a job. Take a look through this link. It explains how in general how it's done.

If you look at the attachments below, they provide the directions specific to your vehicle. This is what I would recommend doing.
I'm not sure what how the battery would benefit from being connected to a charger while driving. It isn't something I am comfortable recommending. I hope you understand.
Let me know if there is anything I can do to help.
Take care,
Joe
