Not quite.
'Resurrection' as I've used it is the literal sense that is used in the NT.
Arising from the dead. If it was the same body that was put in the tomb or if it was magically re-created some way, but essentially having the same person stand before you 3 days after their death.
If that is true, then all the accounts by those people who saw it are true and you'd need to believe in the rest of their advice for the sake of your soul.
As for son of God, you'd need proof of which sense he was using. Either the literal son of god, god made flesh or some weird son of god way.
Essentially, you'd need to go back in time, visit with him and put a video recorder on timelapse in his tomb.
My point is less of what questions to ask to prove Christianity is true, but to first ask yourself, which version of Christianity do you want to be true.
If you were able to go back to the root of it all, then you might know for sure, but if you rely on the undivine decisions of a few people who lived centuries afterwards, then you're a bit out of luck.
Have patience. Someday you'll leave this mortal plane and you'll have the answer to whether you toiled in vain or not.
Or not.
