Moving from D1 to D1.1/D2 on test bed-help needed

Hi guys,
I usually use the forum as a way of keeping up what others are up to but I need a bit of help and a steer.I have a small,ad-hoc, test bed (I work for a large MSO) which is a Cisco VXR7246, with MC28U,MC16C and and a NPE-G1. We have a varying degree of modems on it,small numbers. I use the CMTS mainly for trying out and troubleshooting the RF/HFC features of the IOS plus new CPE that go to the field, rather than the routing/load balancing/subscriber management etc etc side of things.So its a basic set up.
I use the on-board DHCP/TFTP feature of the CMTS to provide the config file/IP address's etc.Although most of the modems are DOCSIS 2.0 compliant, I run them in DOCSIS 1.0, mainly because I dont need anything else.But lately, with the higher tiers of service we are now offering, I need to up my game as things like service flows and BPI+ are running in the production networks-so time to upgrade ;-) Plus as I'm switching between the likes of ATDMA and TDMA and 6.4Mhz with 64QAM/16QAM, it seems only natural I get the IP/TCP side of things sorted.

I dont have access to Cisco CNR (although I can get it from the engineering bods if really pushed-maybe), I'm not a Linux guy either.So I am looking for the bare minimum to get myself up to D1.1/D2. The CMTS has a few servers attached it, all Windows machines, with the likes of TFTP32 and SNMPc on it (plus some internal FTP servers for testing). I know I need to get a config file editor/maker and have looked at the offering from Vulterware-what else do I need? Can I just change the config to point at the TFTP server on the windows machine (same subnet as the CMTS) with the "new" config files?

All help gratefully received! ;-)

cheers
