base is the sr5, next priciest is the offroad package, then the most expensive is the sport package. I know you can't get a longbed in the offroad package.
I personally love my truck and am glad you're looking at a tacoma. I've had my truck since Jan '09 and It had only stranded me once (which was just a old battery) and I replaced the Throwout bearing. All I've done is regular maintenance and I've had no problems with my truck
