1) Supposing the splint is inert with respect to a flame test:
The most likely interpretation is that calcium was present, although strontium can also look orange under certain circumstances.
2. Such a result means that the only possible anions that could be present are nitrate or acetate. Any other anion would cause a precipitate with silver nitrate.
