For what it's worth... I was also surprised by how long I had to hold the lever to shift up a chainring. Now I hold it and don't let go until I've felt the chain move and engage.
I fell a couple of times from a dead stop too. It takes practice to get the hang of it. You'll get there!

) it looks as though your brifters are really high, almost on top of the handlebars. (or are the bars tilted back too much?) Does this position feel okay to you? Why I'm asking is... if you are in the drops, I can't imagine that you would be able to touch them at all. Also, when they are that high up even when you are on top, it pulls them away from your fingers and shoots them straight out. The only part close enough for you is at the origin of the brake so you are working too hard to pull them or get into another gear. (think physics... levers, teeter totters... hard to push/pull close to the fulcrum) If you need them over the top like that, you may have to get a shorter stem to bring the reach closer, not move the shifters towards you.
I don't have to push further or hold it to get it to shift correctly to a bigger ring. I have 105's on mine too and they shift the same up or down now. LBS setting... kept dropping the chain, not getting the whole way into gear without pushing a 2nd time, etc.
Sounds like you are just about set and ready to roll. Hope you continue to have great weather to ride that sweet little bike.
