Need CISCO Guru to help configure new network from scratch! (step-by-step, idiot-proof)

CALLING ALL LIFE SAVERS! :)
Please prove to me that a higher power exists & help save my butt! I thought I could walk on water but CISCO.... ouch drowning here!
I have been tasked with setting up a completely new network at a new office space with equipment I have never touched in my life! I am hoping that I can get some guidance on setting this up correctly from you guys. This is worth 5000 points but unfortunately I can only grant 500 to whomever can help and/or point me in the right direction. I'm a fairly good systems admin but no experience with CISCO stuff :(
O.k., so here's the setup.
Small office - about 20 users.
1 Verizon T-1 Line coming in with the following (made up) IP info:
LAN 220.127.116.11/28 (16 IPs, 13 usable)
WAN 18.104.22.168 (Verizon side)
22.214.171.124 (customer side) subnet mask: 255.255.255.252
DNS 126.96.36.199 & 188.8.131.52
Will be connected to ADTRAN 1200295L1 TSU ACE T1 FT1 DSU/CSU NX56 OR NX64 1.536 MBPS D4(SF) OR ESF (1200295L1). This is an external CSU/DSU unit.
I will have to try to figure out how to configure this CSU/DSU unit as I have never configured one in my life.
I also have a CISCO 871 router and a CISCO PIX 506E firewall. This is where I am completely confused. Should the CSU/DSU be plugged into the router and then into the PIX firewall? Or should it be the other way around?
I need someone to clear this up for me. I have no clue how to go about setting any of these devices up.
The general idea for the setup is for the PIX (or the router) to be plugged into a network switch. I need either the router or the pix to have DHCP enabled for a set of 5 IPs, 10.0.0.1 thru 10.0.0.5.
The LAN will be set up with the 10.0.0.x subnet. A standalone DHCP server with an IP of 10.0.0.10 will assign IPs to all local workstations.
I will have to allow 10 clients to establish VPN connectivity to the network. I have to be able to control UDP & TCP ports through ACL's on the PIX (but clueless as to how it's done).
I am thinking that since the CISCO 871 router does not act as a CSU/DSU, should it be disconnected and returned to the vendor altogether? What is the purpose of having a CISCO 871 and a PIX 506E firewall running together in a small business? Advantages/disadvantages?
As you can see I am completely lost and in need of clear step by step instructions on running the IOS on both of the devices with commands (or is there a GUI that'll allow me to configure all of this?) or an immediate CISCO fundamentals boot camp because I'm due to set this whole thing up on Monday which is coming up in 4 days. I am really hoping for a more realistic option #1. I may also be able to pay a couple of hundred bucks to anyone who will be able to virtually walk me through setting everything up. I promise to provide clear answers to all of your questions.
