None of those mods should be required for 200 wasps, just tune it and save for the inevitable turbo swap.
The Walbro 400L pump is not a great option, either go the e85 one, which is way overkill, or stick to the 255 I would recommend. Even the stock pump should flow that easily. Pretty sure the stock AFM will be fine, as would the intercooler if you were willing to try and push it's limits.
If you want reliability, stick a highflow turbo in, the stock one will let you down eventually.
