As discussed before, a newbie is someone willing to learn and aware that they need to, which is good. A n00b is neither, which is bad. There's a nae-kiddin' academic thungmy about this: the Dunning-Kruger effect.
When you have full STI shifting, which the device in question does, there is nothing hard about drops. Or at least I found it to be so - amazingly intuitive.
As wingpig mentions, you might end up using the actual dropped part once every almost never, but the STI hoods remain win. I'd say 98% of the use my drops get is to give my wrists a break on long rides; the rest of the time I've got my hands on the hoods.
Sora and Tiagra are trademarks of the almighty Shimano Corporation, that make humungous numbers of bike parts and do so so well that even grouches have to admit they're often the best option.
Shimano(and all the other manufacturers) split their products into quality brackets, so you can easily tell how shiny something is by the name. For them it's [no-name guff] -> 2300 -> Sora -> Tiagra -> 105 -> Ultegra -> Dura-Ace.
From Sora upwards, it's functionally the same product, but increasingly lighter and slicker.
