Since your ISP offers you the option to have two different IP, yes that 
the best choice.  Over here I would have to pay quite some money to get 
an extra IP.  So you're lucky I guess.

Also, if your ISP allows PPPoA too instead of only PPPoE, use that 
instead.  It's a bit more optimal due to less overhead.  But it's not 
critical or something.  Just a little and safe optimization.
