with 6000rpm redline and stock gearing, you could redline 5th at around 180mph and 6th at about 265mph (ignoring factors like horsepower and critical speed of all other moving parts). you would be at 165mph around 5500rpm.
with 4.10 you could redline 5th at 151mph, 6th at 223mph and you would need to shift into 6th to get to 165mph at 4400rpm.

the speed limit is 55 and 60 where im from...

With my 228 cam and full bolt ons I still made 30+ on the highway. I drove over 2 hours, raced a full day and then drove back home on the same tank and yes its a 4th gen tank in my car 
Get the 4.10's and forget about top end stuff. You will chew up 6th gear anyhow if you fly around under full load trying to see how fast yer car will go. Its an overdrive gear and its quite small, thus it doesn't like heat and load very much. Enjoy the gears but be prepared to have some whine. My diff was set up by TSP( I bought it used from a guy who bought a TL for the motor) and I get a whine from 50-65mph in both 5th or 6th gear but its worth it. The gears really woke up my cam and were some of the best money I blew on my car all last year.

I hated my 4.10's in my 12-bolt. With heads/cam 4.10's I ran out of gear at the track. You need a high rev limiter and taller than stock tires to make it through the 1/4mi. With more power, the 4.10's become more horrible.

well i ran my car with 4.10 and 3.42 with the same mods on street tires and the car ran the exact same times in 1/4 mph and 60 ft where different. 3.42-12.5 at 112 with 1.9 60ft, 4.10 when they didnt spin 12.5 at 109 with 1.6 60 ft. the results never made since to me but since im still running the rsa's and cause run my car as i run it on the street i went back to the 3.42 cause they more constitent. as for topspeed once i managed to get 171 out of the car with just full exhaust and hptuners and 3.42 which is what the logging software was reading from the speed senor but i dont how acurate it was, with 4.10 never went over 150 so that my results anyway

i have 4.10s and i hit 150 at the way top of 5th gear, probably about 6200 rpms. i just have lid and exhaust for mods aside from the gears. i run about 2100 rpms at 70 mph but i never do 70. you get better city mileage because you can use 6th gear, but your highway mileage is worse because you're just revving higher in the same gear you use to cruise around town. i would say go for the 4.10s though.

yeah 4.10 theres a increase in accleration u just spend more time shifting and im sure if i hade slicks and skines up front with those 4.10s the time would have been better but like it said goodyear rsa on stock rims is a challenge to keep from spining. the only thing i didnt like is running out of gear so quick.
