Full exhaust with sports cat/full decat (preferably the latter 
)
Panel filter
Upgraded fuel pump (if not got ppp but still wouldn't hurt to change for piece of mind)
Re map
Should see you 320(ish)+ as a ball park figure, mine rolled off 345 with the mods listed above
Should you want quicker spool lower down with better response then would recommend a Harvey smith up pipe, and if funds permit then maybe a ported set of headers, won't help your headline figure power wise by much but will make the car better to drive IMO they made a good difference for us

Each to their own I suppose bud, depends on what you want it for, there is no point IMO spending a fortune on a pump with capabilities that exceed what your planning on doing, mine runs a walbro 255 and I ain't had a prob with it, yet others have so opinions will vary on that one tbh. There are other varieties about obviously that are near enough the same as the walbro but have no first hand experience with any so wouldn't like to comment, but I'm sure somebody will soon enough

Again there are mixed opinions on exhausts, I run a miltek and to be honest I'm not a lover, yet others swear by them, there are so many makes about, but I would imagine the majority will say
Miltek
Cobra
Blitz nur spec's
Hayward and Scott
And that's just a couple, do you want it loud or quiet, deep burble or raspy etc try going to a local meet where people have different options on their cars, will probably help make your mind up one way or another
And get friendly with a garage as some of them out there are more than helpful! come mot time can save you time and hassle although a good sports cat should not drastically alter performance tbh just finding a good second hand one as you could be paying for something that's fecked
