The Hurr once again flares its nostrils, and calls up Sethyk on the viewscreen.
"Chk. Now what?"
"They say they know Raive."
"Chrk? Raive?" There is a pause as the techno-squirrel alien rubs its chin.
"Send them in. If they can find their way through... Trrrrrrrr." It gives a strange little trilling noise that could be construed as laughter, and kills the connection.
With a shrug, the Hurr presses a hidden button under the counter and the door at the back of the shop slides open.
Beyond is a store room, home to ten identical black metal cylinders. A screen of slender hanging chains covers an opening off to the right, from which comes the sound of voices and the high-pitched whine of a fine drill.

Vurk recognises the cylinders as containers for liquid oxygen.

Beyond the curtain is a strange, dimly lit corridor. It seems as if someone has taken a larger room and cordened it up with metal plates that swing a few centimeters above the floor on heavy chains. The panels block vision to about 2 meters high, but there is an extra meter above them to the ceiling, riddled with ducts and conduit. The plates are covered with racking units and act as a haphazard storage area for all manner of engineering parts, from the joystick of some fighter craft to pots of nuts and bolts.
The sound carries strangely in here, but somewhere further in comes the intermittent sound of the drill, and a female voice talking in a steady drone.

The panels allow four ways through, from where you are standing. Alternatively you could try going over the top.
On the subject of involving everyone - I always find its trickier outside D&D to define roles as clearly, which may be one reason. I'm using the adventure pretty much as is from the book (except species), which means it isn't very customised to the characters. Further, different episodes aimed at different character types become more spaced out in the PbP format whereas in an evening of tabletop play they might crop up every session. I shall have a think, see if I can modify things.
Meanwhile, here's a situation that isn't about getting past a stubborn shopkeeper
