All you have to do is look at the trunk. What does the number say?
Any E46 can have the sport steering wheel (sport package) and the premium wheels. What you care about is the model (323 is the least horsepower. 325 is better, 328 is better still and 330 is best, save the M3). The "i" represents the sedan model. "ci" means it's a coupe, and "cic" means a coupe/convertible.
Does this car have the sport seats with the adjustable leg supports? That's a dead-giveaway that it's a sport model.
I suggest (by personal preference only) that you do get the sport package. You get better rims, seats and a steering wheel, as well as (usually) Xenon lights and sometimes the chrome window trim. The premium package gives you leather, power seats, wood trim, moonroof, climate control and some other stuff.
My car has the premium package but no sport package, so I have the standard power leather seats and 4-spoke steering wheel and boring 16" rims.
Sounds like you found a keeper. Go for it!
