Putting Alloy Wheels and Bigger Tires on a 1999 Sentra XE

First of all hello to everyone since this is my first post here!

Next, I have a few questions that I hope can be answered by someone with more experience in this area than me.

I have a 1999 Nissan Sentra XE with stock tires/wheels and I want to make the switch to bigger tires (205/40/17) and alloy wheels.

I have the following tire/wheel combination picked out from TireRack.com:

Pirelli PZero Nero M&S Blackwall tires
(http://www.tirerack.com/tires/Spec.jsp?make=Pirelli&model=PZero+Nero+M&S)

and

ASA 17x7 JS1 Wheels
(http://www.tirerack.com/servlet/Cal...elModel=JS1&wheelFinish=Silver+w/Machined+Lip)

So now my question is will there be any problems with installing these on a 99 Sentra XE as far as size and offset (the offset is +40mm) are concerned? The car currently has the steel wheels/hubcaps it originaly came with and 175/70/13 tires.

I believe the wheel opening should be able to accomodate the bigger tires/wheels.?

And if anyone has done a similar modification to this type of car, is this the right size of tires/wheels or should I look at bigger or smaller options.

Also will installing alloy wheels/lower profile tires improve the handling and stability of this car? Because that is the main reason I want to switch over.

If anyone can help me out with this I'd appreciate it, because I have no previous experience with replacing wheels and tires.

Thanks a lot!
