Hello,
You don't need VR for this sort of routing - when there is no requirement to block inter-VLAN traffic.
All You need is:
1/ on EX
1a/ create VLANs
1b/ assign ports to VLANs
1c/ add a static default route to next-hop 10.1.0.1
2/ on SRX (assuming it can reach the internet already)
2a/ add static route(s) to Your VLAN ranges with next-hop 10.0.1.2
2b/ add appropriate policies+possibly src NAT to allow traffic out to internet
HTH
Thx
Alex
