With the toe clips, try to pick up the toe clip as you start moving. At this point, the pedal is almost stationary whereas if you wait until the next stroke, it's moving quite quickly. I tend to drag my foot over the pedal to turn it, then slide my foot forward. You'll find it easier when you go to higher gears too because you won't be as fast off the line (I worked all this out while wondering why I've a near faultless record for getting into my toe clips on my fg but less so with my geared bike ... until I realised on the geared bike, I was taking off in a much lower gear)
