connect sonicwall tz215 with dell 6248p

I'm currently setting up the powerconnect 6248p switch with sonicwall tz215 router. I'm trying to make the switch as simple as possible. The router will do the WAN and DHCP and the switch will route the traffic between subnet PCs and WAN from sonicwall for the internet access.

I have reset the switch to default and vlan1 as management vlan. should I start to create vlan 10 for subnet IP which is same as sonicwall's LAN subnet?

Sonicwall x0: WAN (Fiber) ; x1 : WAN (ADSL2+) ; x2 LAN (10.0.0.x)

Dell 6248p port 44: connection with sonicwall x2

Please recommend any step by step config, thanks a lot.
