We're glad to have you here, Beckaboo.
Just let her be, give her the TUMS and see what happens. I would not concern myself unless she is in obvious distress. She may deliver more or she may be finished. Elongated kits are typical when they get stuck. It happens fairly often in first litters. I'd breed her again... likely she will have an easier time next round.
Do not remove the nest box. She has the right instincts making a good nest and if you remove it now she may kindle on the cage floor or in the litter pan. You have to remember that she is a first timer and is operating solely on instinct. Unfortunately, sometimes there is a delay in the instinctive behaviour kicking in with first timers. She did a lot of things right and will likely do better next time.
