If you thaw a steak that was frozen then it will stay good for a few days, at least. Does this answer your question?
Can You Eat Steak The Next Day If It Was Frozen And Then Thawed In The Microwave?
Steak's a pretty safe meat, shouldn't be a problem for a few days.
Sure you can, no issues with the thawing, if it a grilling steak you can take it from the freezer to the grill.
