What's goin' on?

So I made a mad dash and made it to my goal for my first week of page 150 in Swann's Way. What have I read? Lot's of description of the family's house in Combray. Little bits of the rest of the narrator's life that takes place in Paris usually. All this brought on by the famous madeleines, tea and that hot lemon drink. He wants to tell us about the experience with his aunt eating the madeleines but he keeps getting distracted by other memories. Sometimes these are fun sometimes they are not. Always well written but for some reason I find the rift with the philandering rich uncle more interesting than some other things.
questions:
1) how old is our narrator? is he the same age in Combray I as in Combray II? How much time has elapsed?
2) is there any structure at all to what he's narrating? is it just random?
3) could it all just be random memories tied together? could it?

I regret to say that the person who was writing in the margins seems to have given up around page 100, so no more smileys or little notes on the side. From here on out I'm on my own. I feel like a bomber in World War Two who's gone beyond the range of my fighter escort. Now it's just a few centimeters of sheet metal between me and the cold thin air, the anti-aircraft batteries and the German fighters who stalk me like wolves...
