What type of firewall is it?
Since you have a pre-existing I am going to assume that you already have your servers and workstations assigned private addresses and are using nat. Without knowing the type of firewall I can only tell you, to leave the internal configuration alone, move everything over and you need to reconfigure the firewall with your ISP supplied external address and gateway.
Do the IP addresses of your internal network start with a 192.169.x.x or 10.x.x.x ?
I would definately get a hardware firewall, especially with Windows 98, considering it is end of life and there are no more security updates available for it. You've specified that you have been given an IP address range of 128.174.7.0 to 128.174.7.64. I'm going to assume they they broke this down into a /26? (although that still doesn't make sense, and it's kind of scary if they broke it off without subnetting it, especially without a firewall).
1. You need to find out what the subnet mask is for your IP range.
2. You need to find out the IP of your gateway.
128.174.7.0 is a network address, and non-addressable. So you need to start with 128.174.7.1 (unless this is your gateway). I generally like to leave the first 10 or so IPs open for network/firewall equipment, but it doesn't look like you have a lot of need for that here. ASSUMING your gateway (which would be your router or firewall) is 128.174.7.1, let's start with 128.174.7.5. This leaves 4 addresses available in case you need to add anything additional (this is by no means mandatory, just a personal preference to not have network/servers scattered throughout your IP pool). If this were a /26, then your broadcast would be 128.174.7.63 (we don't know this for sure, but let's just assume).
Taking away .1-.4, giving .5 to the server, this gives us 57 IPs to work with.
Create yourself a spreadsheet, number the first column of cells 128.174.7.1-128.174.7.62, make a second column for the description. Add your gateway at .1, add your sever at .5.
At this point, map out each of your IPs.
When you are ready for the move, assign the new IP to the server along with your gateway and DNS. Assign each of your 98 systems with the IP Since this is windows 98 with NT 4.0, you will also need to change the WINS address on each 98 system.
Without knowing what else is going on, this is about as detailed as I can get with a general plan.
this is the full scenario i broke it down to make it easier.
You are the Network Administrator for a company that is moving to a new location and wishes to upgrade its computer systems and double the work force. Currently, the company has 35 employees running Windows 98 on a Windows NT 4.0 domain. 10 employees are in management, 5 are in programming, 5 are in sales, and 15 are in graphics and development. The company wishes to create a research team and provide you an IT staff, as well as increase the size of the other teams. At the new location, the office is already wired for Internet connection. The Internet Service Provider has issued the company an IP address range of 128.174.7.0 to 128.174.7.64. Provide a proposal that includes a Server solution, the amount of new computers, printers, and servers to purchase, and the Operating System to install. Also create a plan for IP addresses of the computers and servers. Finally, add network printers and shared group permissions for printers and file server storage. Be sure to provide the groups you create and the members of the groups.

1. Do you have a firewall?
2. is the current office already behind a firewall?
3. If 1 and 2 are no, are you planning to implement a firewall (answer needs to be yes, even if it's a cheap linksys)
If your servers are already behind a firewall, and you are planning to use a pre-existing one, that makes all the difference in the world on how you should proceed. It sounds as if you have been "volentold" to handle this, so my explaination would also depend on your level of expertise with this subject.
