At the current lease interest rates it's worth putting money up front to reduce the overall cost of the lease IMO. I actually paid the whole lease when I picked up the car which saved me 4 digits.
Some people say you should never put money down on a lease but I honestly have yet to hear a compelling argument why... it seems to just be misinformation that people repeat without really knowing what they're talking about, like when people say don't get a plasma tv because of burn in.
Residual sounds good, make sure you get at least a 3% discount off the MSRP of the car and make sure they base the residual on the MSRP of the car NOT the discounted price of the car. Also watch out for all the little fees (admin fees, etc...) that dealers seem to be coming up with.
... and enjoy not having any provincial sales tax to pay!!
