Had my 156 GTA for 4 months now and already I want to tackle the handling, stopping and go

but I have zero pennies
Well the brakes certainly need attention - they are getting more and more badly warped, so when I come back from Ireland at the end of the month, I will need to upgrade the brakes - I 'll see what Jamie Porter charges for the work if I get the kit from Alfa. If I recall I saw someone on here commenting it was around £500 or so?
On the handling side, I really want to improve this, but can't afford the coilovers, BUT, as the brakes are to be done, it may be a cost saving to do them at the same time???
Then there's the mid range -there are some flat spots in the car's driving (there are some hesitations that coudl do with ironing out!)- how will a remap improve this? Who does the best one? I guess a CDA kit would also be useful to extract the best from a remap?
Finally the exhaust - I love the engine sound, but it really could do with a touch more meatiness in the exhaust, so, Ragazzon + silenced centre section, or CSC +silenced centre section, or Supersprint rear box and a.n.other make of silenced centre section.
I so wish I had some spare cash
