As far as tinting... it depends on your preferences and your cars condition and how much you care about it. One reason I tinted my car was to protect the leather interior. Secondly, for looks. And finally, for privacy. I got it done with a lifetime warrenty for $150. But, if I had to do it again, I would get titanium tint- this is better quality and more reflective(not like mirror though). Get your yellow pages, call all the tint places and get the best price.
As far as spoiler I have the stock spoiler... if you can call it that. It looks more like a lip. It is alright. I'm not too impressed with it. Somebody on this forum has a spoiler from a Maxima. You can also get new ones online. I would just buy one online and pay for it or go junkyard hoping and try to find one that will fit and maybe even in you color. Not sure if the second-gen will fit but they are kinda rare. I'm sure somebody else knows this.
