I have an Eclipse Performance chip in my ECU which raises the boost from 0.9 to 1.1 bar, which gave me a bit more power (And means I can use 97ron)
full exhaust as above, but go 3" and leave the headers as after market ones are supposed to make spool a little worse from what I have heard. I went sports-cat rather than decat. get 100cell, not 200 cell if you go for a sports cat as 100cel is less restrictive.
