The only way in from Earlswood really is the A34, and it's not so bad. Not anywhere as bad as Kings Heath.
This is my neck of the woods. From Earlswood you could:
- go through Tidbury Green
- past Whitlocks End Station on Haslucks Green Rd
- just before Shirley Station, left on Green Ln
- follow straight through on Aquaduct Rd, Windmill Ln, Priory Rd
- left onto Cole Valley Rd (you're picking up one of my commute routes from here)
- left then right onto Wake Green Rd
- right onto Yardley Wood Rd
- left onto Woodstock Rd
- at end, right then left onto Brighton Rd
- which brings you out onto the A435
- from there, you know where you need to get to and can work out how to go from there
