Best network design and how to setup Sonicwall TZ00 and DSL modem

Current setup:

SBS2003 Standard as domain controller (192.168.15.100). WAG54G2 DSL modem/router (192.168.15.1). Both working fine but plan is to upgrade server to new H/W and OS (SBS2011 Std) and add Sonicwall TZ200 with wireless.
The WAG54G2 is setup using PPPoE and performance is very average.
My plan is to leave the WAG54G2 with current setup because it's working and I don't want to interupt live network so I would like to use a spare device (Open Networks iConnect 625) with the sonicwall.
The server handles DHCP/DNS and this will have to stay the same.
I need a recommendation on best practice in this scenario and how setup the 625 and TZ200.
Do I need to setup the 625 in bridge mode and setup the sonicwall to handle NAT i.e. configure the sonicwall to connect to my ISP?
I prefer to use the same address scheme on LAN if possible so as to avoid having to re-configure the sever.
Please assume I have basic networking skills and provide clear/specific deatails like where to plug which cable.
i.e. The sonic wall has a Lan/XO port and a Wan/X1 port. Where should the Cat5 cable conenct from modem to TZ200? where should cable go from TZ200 to network switch?
Is there a different configuration that is recommended? i.e. use the 625 as gateway and port forward traffic to TZ200 which then port forwards to SBS?
Thank you in advance.

I'd suggest not usin the sonicwall wifi. Get the regular one for cheaper and use any old access point. I'm curretly using that setup with some buffalo wzrhp simultaneous dual band aps. I can put them wherever and bury the sonicwall in the closet.

Oh, and don't keep using the linksys as the gateway. Use I as an extra ap if you want but let the sonicwall do the routing.

K. Nothing wrong wit their wifi it works great. Tricky thing is out of the box it's a separate zone. So If you want wifi to work like most other gear you have to manually bridge it. It's a common annoyance so there are plenty of articles on how to change it

After setting up everything on the side so as not to disrupt your users, plug the modem into the wan x1 and plug your LAN into LAN x0. If you uncheck the "only allow sonicpoint wifi" box you can use your linksys as an additional ap. Search sonicwall 3rd party ap for lots of articles on that.

Definately keep dns on your server, but Why not let the sonicwall handle dhcp? It does a good job, has nice options, and has the ability to do the network boot stuff. I setup my Acronis pxe server in under 5 min. Now I can plug in any PC, network boot, and deploy an image. I love it.

Thanks for pointing out factors relating to wireless.

Keeping DNS on server is purerly based on other documents I have read which recommned this.
Not sure about SBS 2011 and if same is recommended?
I deally I would like users to have internet access if server is down so it may be worth me investigating and testing sonicwall as DHCP server.
Havn't used Acronis pxe server but what you share about your experience sounds great.

My main concern initially is to understand how to get the 625 and sonicwall setup and serve internet to LAN then I can play with wireless etc.

In summary, are you saying: setup 625 in bridge mode, configure sonicewall WAN/X1 PPPoE settings and connect as per your post?

I have no experience with a 625 but yeah that sounds right.
Take screen shots of your old setup, port forwarding, ip ranges, etc...
You can setup the sonicwall off to the side with just your PC attached to no affect your users. Then when the time comes just switch em. Only a min or two of downtime. You have backupmx setup right?
