I can only answer number three, since I have never owned a TM vsr-10, and cannot answer the other questions.
3. For barrel spacers in any bolt action rifle, I typically never buy them offline. For twenty bucks for a 2-pack I find it not worth it. I went to the local True Value (or Home Depot), and bought some electric tape. I then wrapped it around the inner barrel until it was a relatively tight fit in the outer barrel. I did this evenly spacing them on the inner barrel, and this becomes a cheap method to make barrel spacers that can save some money.
This can help increase the accuracy which you asked in your fourth question. The spacers limit the barrel vibration and wobble, and can help steady each shot. A simple test to make sure the spacers are affective, is to put the rifle together, and with the end cap off, put your finger on the inner barrel and wiggle it around. The barrel should not move much, due to the spacers keeping the inner barrel steady.
