Tints will look superb on the rear screen and rear door windows. It will have factory tints all round so leave the front alone otherwise you'll be risking having unlawful windows.
85% attenuation at the rear door windows will give you a nice dimmed interior as well, thus improving foward vision due to better contrast ratios.
I had a P11 Primera - they're extremely nice cars to drive indeed with handing that can shame many true sports cars (I tried back to back car swapping with a friend who drove a Jag XK8 and he was staggered at how firmly the P11 dripped even at silly speeds in wet bends). THey DO need to have a full four wheel alignment to give of their best. You also need to use decent tyres. These cars wear tyres very evenly due to the superb suspension geometry so don't be afraid to spend Conti or Michelon money - they'll last long and serve you well.
Probably no need to lower it, but the suspension is quite stiff so if you do so it will still work superbly. Chrome is a no-no for my eyes. A subtle spoiler bottom of tailgate will make no difference at all to the drive but gives a nice finish to the rear, which is a bit 'slotty' to look at. It's also a good reference point for parking the thing - rear vision is not the best.
THe P11 (96-2000) is a very underrated car, finding favour with pensioners and taxi-drivers. They drive very differently indeed as mentioned earlier.
My only minor gripes were that the engines (2.0 SR20DE especially could be a bit vocal, but still smooth and indestructible) and that the braking bite was a bit lacking initially. This was a feel thing for me as the cars do stop brilliantly, aided again, but a superb chassis that keeps all the wheels four square on the tarmac regardless of whatever feat you're asking of the car.
Go enjoy!!
