Does "at my house" needs to be changed? Does it mean inside my house or just in the yard? No, it is fine. It indicates at your place of residence - it does not specify inside or outside.
and
Should at New Year be changed to on New Year?
But some people say at Christmas. "at New Year" indicates at the time of the New Year; "on New Year['s Day] indicates on January 1st. "At Christmas" = at Christmas-time.
