Man, I really wish I could offer you advice based on experience... I just didn't want you to think people were ignoring you. I wish you luck on your combo. From what I can see it looks like a good streetable one. I think the 190lph fuel pump would be a bit much unless you're going to add a Blower down the line. 155lph would probably be enough. Don't take my word for this man, get a second and third opinion. Stock fuel rails are probably ok. A friend of mine said 1.6 rockers are better in the longrun, again, I can't speak from experience. Yet anyways. 24lb injectors should be good in my opinion also. E303 cam should be a good streetable cam since your combo doesn't look very radical. This is just based on hearsay bro. Please make sure to get a couple of other opinions. If noone else here responds, perhaps you can consult a reputable engine builder in your town. Goodluck.
