Okay, Firstly - No point in upgrading your brakes, unless you plan on doing any track work. Only upgrade to them should be some decent pads..
Secondly, By the time you purchase both a shift kit, and replacement diff gears, and have them all fitted (because i'm assuming you cant do it yourself) you could have considered the possibility of a manual conversion.
Thirdly, No such thing as a power chip, you can however have your factory memcal re-tuned..
And last of all, you left out the more basic mods, such as a cold air intake system, and an upgraded exhaust system..
no point upgrading brakes? its not like its going to do any damage. surely greater stopping power is always a good thing. could save his life one day as the VN brakes are smaller than any other v6 model commodore, and really arent that great.

9 PSI SC14 Intercooled :: Genie headers :: Twin cats :: HM Twin 2.25 exhaust :: 3.45:1 LSD
1. Memcal/Tune
2. Shiftkit/Manual conversion
3. LSD with 3.7s, or 3.9s if you really want them
and brakes somewhere in there if you decide to do them. always a good idea to update them, or at least get some decent pads for them.

still want some more opinions
cheap upgrade would be VP brakes. same as vn v8. would cost **** all to do and might make a bit of an improvement. possibly a 1 inch master cylinder as well

yer iv looked in to all that stuff, upgrading is probably the last thing i would do if that
a larger throttle body is a total wast in truth the v6 standard throttle body was extremely close to maximum flow for that engine and besides after that the elbow slows the airflow any how
if you ask green foam or some of the other guys here they will tell ya the same you may get slightly better response time but its un likely
and as for a tune ask greenfoam http://forums.justcommodores.com.au/...greenfoam.html
im sure he will hook you up and around here hes known to be the one to talk to about it good luck
i wont tolerate cretins aiming to cause problems here at jc and nor will i hesitate to let the moderators know

leave the bellmouth in there.. theres no point removing it
Theres no point in removing the bellmouth, or fitting a larger throttle body. What's the point in a 5mm increase in the TB body, if the elbow is left unchanged....Your just throwing away good money. As far as removing the bellmouth goes, i've said this to people before, if you want to modify your engine, or any other part of your car for that matter, then this is done by replacing, or fabricating a part, that is superior to that of the one you are replacing. Not by simply removing that part all together....
You can upgrade to the V8 throttle body, which is 65MM. Anything bigger than that is pretty much useless as the elbow is 68MM.
Honestly, I've always been one to say this, the first thing you ever do to a car is improve it's brakes. Might not have to be by much, but I've been told on the VN V6's they're shit. (I've got the Sports pack, so they come with the V8 brakes). You can go to the V8 brakes if you want. For something more, there's the VT brake upgrade, or if you want some insane stopping power, you can do the same as someone else on the forum, and convert it to the monster VE brakes. As for brake pads, everyone has their personal opinions. I like the feel of the QFM-HPX pads. Feel very nice under your foot.
Once that's done, then you can start doing performance mods;
These are in no particular order, really, just to help you.
1. Diff gears.
a)Don't do much highway driving? 3.9s or 4.11s
b)Do some regular highway driving? 3.45s or 3.7s
2. Get rid of that single spinner
a)Love doing burnouts? Mini/Full-spool is your only option
B)Not a burnout boy but want the added effect of a twin spinner? Then get an LSD
3. Greenfoam tune. $55 or so, it'll be some of the best money spent
4. A nice shift kit in it. I've got a manual, so I'm not really informed on shift kits.
5. Nice set of high-lift roller rockers. You can go the 1.8 ratio rockers on the VNs. Get them and you should notice an alright increase. After that though, it may be beneficial to get another tune off greenfoam.
6. Forced induction. You haven't got much more choice now without opening up the motor.
