The "important" differences can be seen with the srm.
The deckplans for the enterprise-d with some modifications (actually alot)could be made into nebula plans, I did this before and it took a long time and before you ask no I do not have it anymore gave it to a new player/gamemaster who was just starting his first adventure..
There are past threads that talk about the nebula,particularly its modular pod.
I don't know if this might be helpful. But the bridge of a Nebula-class was featured on a past episode of DS9.
It is why a back issue of Star Trek: The Magazine (#11) did an isomorphic drawing of the bridge in its feature technical briefing of the Nebula-class.
As for the rest, you're going to have to be creative but like most Federation starships, the interior designs are basically the same. The placement of critical areas (with the exception of the main bridge) may differ.
------------------ Anyhoo, just some random thoughts...
I'm also preparing to transfer my players to a Nebula. I have the Galaxy-class deck plans on order from Amazon.com and they should be here next week. The saucer sections should be virtually identical; ditto for the nacelles. The engineering hull of a Nebula is shorter, but I'll probably still use the Galaxy plans and just tell the players that every room is a little bit shorter fore and aft.
The equipment pod is going to take a lot of work, if I decide to actually lay out all the floorplans. I may just decide that there's a turbolift leading to a central control room and a simple network of corridors and Jefferies tubes that lead to equipment. I'm thinking of saying that the eqipment won't need hands-on maintenance very often, so the characters won't go there any more often than they go into the nacelles.
What kind of pod were you going to mount? I'm leaning toward the weapons pod, since I want to assign them to the Neutral Zone patrol and run "A Fragile Peace".

Weapons pod? Come on, give they a big sensor pod. That way if they get in some fleet action, they can be ordered to fall back and relay sensor information to the fleet.
To add insult, maybe there's a ship assigned to defend them.
I'll bet that after 5 rounds a combat, the captain will disable it's escort, go into the thick of things and save the day.
Bob, that's just mean! My players are on an Ambassador with lots of "personality quirks" (ie, rust bucket) right now. They've earned a better ship, so I'm going to give them a Nebula that's new enough to be in good shape and just old enough to have all the bugs worked out. I'm hoping they can keep this one for a while and plan on letting them upgrade her occasionally.
