I am hoping that doctorwayne will jump in here with some actual solid advice as he seems to be "The Man" when it comes to detailing steam locomotives. But I kinda recall that there are three major types of feedwater heaters ... the cylindrical ones like the CNJ and the CN had, (called the Worthington, I think,) a boxy-looking one that I think maybe NYC and CNW used, both types usually sat above the smokebox in front of the stack. The third style of feedwater heater, as I recall, was contained within the smokebox and was not visible to the casual observer.
Cast brass examples of the Worthington feedwater heater are available from Cal-Scale and Precison Scale, if I recall correctly. I think they also have the "boxy" one, too, the name of which escapes me. For piping, you'll have to ask doctorwayne.
For the siderods ... I know that there are metal "coloring agents," called, I believe, "Blacken-it" which makes metals black, and "Weather-it" which has a brownish cast to it as it darkens the metal. I have never used either and so have no first-hand knowledge of how they work. In the past, I have painted side rods with Floquil paint, mixed to look like an oily coating on machined steel castings and the baked them at 200° for 20 minutes or so and then allowed to cool down as the oven cools down.
As far as filling in holes in a cast metal boiler, I would probably build up thin layers of Squadron Green Putty ... it dries relatively hard, sands quite well, blends well and takes paint very well.
Others may have differing opinions as to any of what I have said ... I don't claim to be the last word on anything!
