TDi do a standard stage 2 DIC these days. They give better low and high cam performance over most other DIC. Iirc they do supply just the cams now at around £950. Highly recommended as they do perform superb, skunk2 do a DIC but I wouldn't fit without at least an uprated chain tensioner, that goes for any cam upgrade. TDi's should be OK on stock one but I still opted to be safe and replaced the whole lot.
Whilst in there it's worth doing valve springs to rev to 9k as you have the FD2 pump. May gain more power if you opt for a huge cai and 3" exhaust. I didn't bother as cost to gains just weren't worth it.
Toda A3 cams offer better performance but require the uprated springs and tensioner.
FD2 cams are also good but peak at around 245.
FD2 pump you've already done.
CPL manifold should see you just fine up to and over 250bhp. It apparently has good top end but loses out slightly for mid-range compared to Toda / Teg, wouldn't change it personally.
Exhaust is the big one, K20s love a big 3" single exit. Every single graph I've seen shows 3" on top even on stock cams. TDi's 3" is the one I'd go for, I went solid fabs as I got a good deal. If I was buying new however it would be TDi's. Warning, they are loud and droney!
Failing that a decent 2.5" (single exit would be better) will do fine, they are easier to live with day-day and may still net you close or around 250.
Not required and rather expensive but port and polishing the head along with raising the compression ratio gives some gains but you need decent fuel for the CR and the cost for gains is slim.
