It's an awesome bike. If you have the US model (which i quess you have) it's a must to change the stock exhaust. You must also consider to change the rear sprocket with a bigger one to make it a little bit snappier.:bonk:

Great bike, I've had mine since Nov '07 no complaints. My advice before you start buying and swapping stuff go ride the bike and see how you like it.

Those are the first things I would change. Second of course is the suspension work. I just had mine all done and it makes a big difference.

Ride it as-is for now. Set up the sag, dial in the clickers and see if you need some minor handlebar positioning.

Then if you have some coin laying around, the popular choices for more power "snap" are an exhaust and maybe a 1 tooth larger rear sprocket as others have suggested.

Disclaimer: I do have a aftermarket exhaust, but I truly do not know why because it's not like my cornering speed is just so darn good that I need more bark and pull after perfectly hitting my lines corner after corner. :bonk:

As most people say the 08 suspension is one of the best out there.

Change the fork oil so that you have a 'fresh' point of reference and then dial in the suspension and get the handlebars adjusted for you. Get fresh tires, esp the front tire as tires can make all the difference with this bike. Then spend time riding the bike and getting use to the handling and power before you start thinking anything else.

I would buy a new chain and sprockets - stock chain is junk. Ride it, set up the suspension for you before spending on any other bling. It makes no since to put a bunch of money in it - you will never get the money back, ever. If you hate the power(determine it is a little too soft) consider a better pipe (stock pipe is very restrictive) and that is it.
I wish I could have taken my own advice......on my 03 and 06:banghead:

The chain is indeed junk, but if you rid yourself of it soon enough, and use a good enough replacement chain, the stock sprockets will last at least a year.

Backing off on fork compression damping might help reduce the front end push. My '08 450F was at stock settings, but got better and better as I turned down compression damping. (of course, if you are an "A"class MX rider that might be a mistake!)

About the pipe replacement, you don't need a complete exhaust to gain the low-to-mid-range thrust, just the muffler. The stock header is fine, mated to my FMF Q4 muffler.
FWIW I also have the complete FMF Megabomb/Factory 4.1 system, which works good but not much different than stock header/Q4 muffler. Needless to say, just buying the muffler is a LOT cheaper!

What psi your front tire at, and where have you set the rear sag?

Yes, backing off compression damping might help. The top is the compression damping adjustment. 7 clicks out is WAY too stiff for me. (my suspension is stock, not re-valved)
I'm 165 in street clothes, and for moto, 3 clicks from full-soft worked wonders. Sometimes I even go full-soft compression damping, depending on the track.

psi . . . YamaLink is talkin' about tire pressure.
