For the thermos, I really like Hydroflask. They have some different lid options, and lots of different colors.
To add to that.... They're great for hot or cold and can keep that temp all day. The flip top lid isn't totally spill proof, but pretty close.

I love my Timbuk2 bag. It's perfect for me for everyday stuff. Padded laptop pocket, some smaller pockets for pencils and stuff. It's pretty much waterproof. Love that thing. Only downside is it's just a little too small for a weekend trip.

I use this wallet. It's thin, lightweight, and nothing fancy. It's made of tyvek paper which is pretty durable. I don't beat up my wallets much though. It's got enough pockets for me, it's thin and light. Previously I had a duct tape wallet. This one is definitely a couple steps up from that.
