Sounds good - I had wondered where to keep money (other half has a money belt) and valuables. Padlocking my backpack won't really help I'd imagine.
I had a money belt but it was a pain in the balls so i ended up not using it. My backpack didnt have a padlock or that wire mesh stuff. Personally if a bag has a load of security on it, it means "steal me because i have good stuff in" people who want to get in will just snip the wire anyway or pull it open. Just dont pack things like a rolex and 2 laptops!
I took the following -
Suppose to be a day or 2-3 day ski backpack. Rubbish, I had it for just over 7 months and was probably too much
45litre backback +15litre (sides and top)
1 jeans
flipflops
trainers
2 swim shorts
1 shorts
5 boxers
5 socks
2 shirt
5 tshirts
1 dry towel
small pillow
silk sleep sack
zip clear bag with the following - toothbrush, toothpaste, paracetamol, battery shaver, electronic stuff like usb drive, camera charger
The slik sleep sack and small pillow came in very handy on the odd occasion my bed had ants on and the pillow looked like someone had used it as a tampon!
I did laugh when i got off small boats onto island in thailand and fiji and watch as people struggled with their 80litre monsters or wheeled case as I held mine above my head
