Mechanics questions

[stripes1977]

I've worked two scrimmages this year and I've seen a couple things that I thought were no-no's:

1) When signaling incomplete, I've seen some older officials give the incomplete signal followed by the time out signal...isn't this redundant?? I know that some clock operators are ignorant, but as a general rule, shouldn't we assume they know that the clock would stop on an incomplete pass??

2) Sideline play, ball carrier is tackled in-bounds and the play results in a first down. Wind the clock to show he is inbounds and THEN stop the clock for the first down correct? (The one question about this is how many times do we wind it and how many times do we give the stop clock signal? I've been taught that we do everything in three's, so do we do the wind twice and the stop clock once or vice-versa or what?)
