i've often seen the jack-rabbit warning, but never anything about accelerating "too slowly".

-- basically you need to get into that higher gear as quickly and efficiently as possible.

i don't think you can generalize on this point. depends on what's coming up next in your driving (e.g. imminent stop/slow down). also, there are likely differences in what technique is best depending on manual or auto.
