Upgrading parts on Fuji Panic 3.0 I want to upgrade some gear parts on my current bike, which is a Fuji Panic 3.0
I don't really know if it will be compatible though.
The bike: http://www.bikepedia.com/QuickBike/BikeSpecs.aspx?year=2006&amp;brand=Fuji&amp;model=Panic+3.0

Parts i will be equipping/replacing with:


Shimano Alivio ST-M4000 Shifters 3 x 9-speed
Shimano Deore RD-M592 rear derallieur MTB SGS    
Shimano Deore FD-M590 front derallieur Top Swing OR FD-M591 Down Swing
Shimano Alivio CS-HG300 Cassette 9-speed
Shimano Alivio FC-M4000 Crankset MTB 40/30/22, 9-speed


Parts are not final, i can for example replace the M592 with a M591 for about €5 cheaper

I also noticed that some of the parts come in diffrent versions and designs, for example the cassette comes with different ammount of cogs: 11-28, 11-32, 11-34, etc.

How do i know which designs/versions to use? The Crankset (some length in mm), Front derrallieur (some angle in degrees) and rear cassette (ammount of cogs) have diffrent versions

Is there any other parts i would need to buy? I was thinking i could re-use the rest on the bike.

Everything on the bike except the shifters are original. I could also just buy Claris shifters and use current parts but since i bought the bike used and the gears seem somewhat clunky i decided it might be best to replace the gears instead.

Thoughts?

Thanks in advance!

EDIT: The parts will cost around €160

EDIT2: Thanks for all the answers, I will be buying a new bike.
