My thought was create a bridge with 2 x CPE510.

If you really need transparent access between B1 LAN devices to B2 LAN devices, bridge mode is the preferred mode.

If you just need Internet access for B2 LAN devices, but no access to B1 LAN devices, AP mode on B1 CPE and client mode on B2 CPE would be much better in terms of bandwidth savings.

What else is required to get the bridge connected to WIFI in B2 working, Can i just plug a Wireless router into the LAN1 port of CPE510, if so what model and whats required to set up (modes etc confuses me).

Why a wireless router if using bridge mode with the CPEs? A dumb AP would fit better, else you have no advantage of bridge mode.

Even if you use AP/client modes on the CPEs, a router would not be necessary, since the B2 CPE could be configured to behave like a router (AP client router mode would make B2 CPE a client on the WAN side and a router on the LAN side), so any AP would fit also to serve WiFi clients at B2. I would recommend TL-WA901ND as a cheap AP or an EAP as an indoor AP, but definitely not a router.
