There are no finished induction kits out as yet. You'll have to hold fire a few months. Forge and ITG have them in development. Blueflame and miltek are working on exhausts.
While the direct air intake and exhaust are in production it might be worth sorting out the suspension and brakes first. Would be best to get the best handling for the car before adding more power. If money is not too tight I'd say :
Weitec Coilies
Rear ARB
Strut Brace (Not sure if one is ready yet)
Big brake conversion
This would give the perfect base for power mods and would give you time to get it all done before they are released. Warranty will be lost on all parts changed and some that will be affected by the part you change. Obviously a car isn't supposed to go wrong in the first three years but it will be a risk you will have to take. Some won't mod because of warranty but other will, it's down to personal preference.
well i can get them from work as part of the company i work for imports them, but if you wanted a set i could sort you out a price
As for custom exhaust as mentioned, it's ok providing the company making it know their stuff, but how can they develop it? Blueflame for example have been testing one for a while and made some revisions, not reinventing the wheel but its not always as straight forward as slinging on a big pipe.
