So for $35 you can drop almost a quarter pound. Your stock saddle is probably a boat anchor. You can probably find an inexpensive saddle at least 100g lighter. As mentioned, wheels are a big one, you can probably drop at least a pound with some cheap Fulcrum's or Vuelta's. A 105 group is going to be much lighter than your Sora stuff. A lighter cassette is a big one to look at, lots of weight to drop there. If you're really concerned about weight, buy a cheap scale at Walmart and weigh your parts.
I feel like your advice isn't correct. Because every item on his bike is heavy, you are basically telling him to build up an entire light bike from individual parts. That is the most expensive way to acquire a bike unless you are your own mechanic, very experienced at finding quality used and takeoff parts, and very knowledgeable about what is light, cheap and good and what is light, expensive and crap. A few upgrades would help an already light bike, but not this one. IMO It would be much better for him to save his pennies for the kind of deal you get on a fully built bike more in line with his desired weight. Then a few judicious upgrades to that might be in order.
