If I'm reading this right, you have a wetsuit and "access" to the rest meaning borrow. Also, I have no idea where you live or dive. All that said, I'd probably suggest you buy gear for yourself in this order:
1) mask/snorkel/fins
2) regs
3) bcd
4) dive lights
5) reel/smb
I think taking some specialties, especially the Rescue Diver course, would be a good idea too.
I have some of these things for sale - shameless plugs below:
