02 V7XC Stage lll upgrades

[cap10-13]

I have an 02 v70xc 2.5T looking for some information on upgrades. Don't want to do this twice i would like to get it right the first time. What I'm looking to do is Stage 3 upgrade do's & don'ts. Looking at;
Snabb exhaust system(complete)
Bad Sweede springs (2" lift) I'm 6'4" car sits little low for my bad knees. What struts would work best with? Saw a suggestion about using xc 90 axles with the springs?
Ipd torsion bars F&R
Turbo ???
DO88 radiator & Inter-cooler
19" rims
ipd ECU flash or soft tune
I rather get the lessons before I do it and have to spend my weekends under the car. This will be mat daily driver so i can't afford to brake things because it wasn't the right combination of parts.
Any help or websites would be greatly appreciated. Thank you in advance for your Help.
