I need help!!!

I need some major help! I just finished up my ver9 swap into my 00' rs and now have some CEL codes come up. They are pretty random codes and in my eyes aren't really linked to each other. So I don't want to start dumping money on every code that flashes at me and wondering if anyone that has done a swap similar to mine (ej207 swap) has had the same issue.

Codes:

0123- tps

0118- coolant temp sensor

0113- intake air temp sensor

0108- manifold absolute press/ barometric press circuit

Everyone input will be extremely appreciated.
