new guy looking for engine building tips

Hi I have an older 4 bolt small block 350 and looking to convert it over to tbi by installing the heads and intake off an LO5. It will be my daily driver so my goal is to build an engine that is fuel efficient but not completely gutless. So now start the questions. What sensors if any should I remove? I plan on running a Dakota Digital cruise control so I want to keep the VSS. Does anyone know of a good place that can burn a new chip for me? Would I be better off running stock exhaust manifolds or should I upgrade to headers? Should I use a tbi spacer? Should I run the tbi cam, the carburetor cam, or some aftermarket cam? If any help here would be greatly appreciated and if I overlooked any aspect that should be addressed please let me know. Thank you
