Stick with your 7mm til it needs replacing, by which time you might be able to replace with shiny new kit.
Paracord for everything non-climbingy. Laces lanyards and drawcords etc Cheap as chips, strong. But make sure to get the quality 7 inner strand stuff.
Can get it on eBay by the metre.
Compression sack. Sure use it, unless you have loads of unused space in your bag. Just don't store it fully compressed at home or when in camp/huts.
Don't take your frame out unless the pack is designed to be able to do so. Otherwise you could be transferring stresses to other parts of the pack and weakening/damaging it.
Condensed milk? Ick! Or could get the tiny individual uht pots. Poundshop sell em in packs of 16 or 20. Store inside your cooking pot/mug, or a small Tupperware box, for travel purposes. Carry some powdered milk to make it go further. (Or just use powdered milk but not quite as nice by itself)
