If you're talking about actual toe clips, you stick your foot into one first, and don't even try to get into the second one till you're moving. Once you're in motion, just the tip of your toe on the edge of the pedal will generally flip them around so you can insert.
As to "drop" bars; I see all sorts of people riding around with their hands glued into the "drops"; the lowest part of the bar. It's as if they think that's the normal riding position...It isn't.
Your normal position should be with your hands on "the Hoods", that is, the brake/shifter hoods. If the bike is fitted properly, you should have a nice, comfortable straight-backed position with your hands there.
If this is not the case, you may need a different stem; one shorter, longer, or at a different angle.
The "drops" are used by recreational riders as a wind-cheating position, or maybe to gain a little aero advantage going downhill. Advanced riders use them for sprinting.
The top of the bar is normally used for climbing. Allows you to shift back on the saddle for max leg extension, and to maintain an "open chest" position for deep breathing.
