I've seen TRD Offroads in Canada, but they appear to be either an 05 or 06 model. You could try asking the dealer if it's possible to special order one, but you may have a bit of a wait time before they recieve it.
As for the locker vs limited slip, if this will primarily be a street truck you'll want the LSD and if you're looking at seriously offroading it you'll want the locker.
My opinion is that LSD is far more useful for street performance. The truck launches harder from a standstill and you don't have to worry about having one wheel spinning on slick pavement, loose gravel or ice until you finally inch far enough forward to get decent traction like you would with an open diff (and the locking diff is an open diff when unlocked). In these cases an LSD is useful because it will transfers power to the wheel with the most traction, whereas an unlocked/open diff will transfer power to the wheel with the least. Also, a locker is pretty much useless in these situations because you're not going to drive around on the street with the locker engaged, and by the time you do engage it you could've inched your way forward enough that you won't need it anyway.
An LSD is also useful for towing, particularily if you tow a heavy boat and want to pull it back up a wet launch. A locker will also help you get back up the ramp but it's not as useful for general towing since you can't drive around with your diff locked.
As for offroad performance, a locker will be a big help if you're into rock crawling or mudding* (not much desert around Newcastle I'd imagine), since in the former you can frequently have one wheel off the ground and in the latter both wheels can have next to no traction even though both are burried in the ground. In these cases a locker has the advantage because it transfers equal power to both wheels regardless of traction (or lack thereof). Also, for technical offroading a locker is great because it gives you more control over your rear wheels, so you'll be able to better control your vehicles speed and grip over a harder obstical.
So in the end it comes down to choosing the right tool for the job. If you want maximum street performance and will only do some mild offroading then a locker is a waste and you'll wish you had the added street performance of an LSD... but if you're planning on seriously offroading this truck then an LSD will only have you wishing you had the added offroad performance of a locker.
* Note: By mudding I mean real mudding and not simply driving through dirty water... there is a difference... a big difference.
