Dear Jim
To be as much as clear possible, we are going to answer point by point to your numbered questions:
1 - Normally our mounts are ready in less then 20 minutes. Due to our counterweights, mounts and tripods use a comfortable knobs system, the mechanical setup require max 10/15 minutes and, with a bit of experience after some setup, a user can be ready in less then 10 minutes.
For the M-zero obs it will be required more time only for the first mount setup, since in order to have a safe shipment, the pier comes disassembled and must be mounted at least one time from the user (see M-zero Obs user manual). Then, once the mount it is assembled on the pier, the product it is really compact and light, so it will become something "place and play".
The standard Polar Alignment procedure can takes about 5/10 minutes, however, with the help of devices such as Polemaster or iPolar you can be ready in less then 5 minutes.
Finally, if you place the mount inside a small observatory, with the special StarGo.exe Park/Unpark function, the mount can remember the last session position and be ready in few seconds.
The M-zero most of the times can make 30sec exposure without autoguiding. In the best conditions, sometimes, it is possible to achieve up to max 2 minutes without autoguiding. In this case, please be sure that a precise and accurate Polar Alignment has been performed. For 10 minutes exposure, guiding is suggested.
2 - From what we see in the EAGLE3 product page, it seems to be compatible with the Primaluce lab Vixen style dovetail ,

in this case, it will be possible to mount the mentioned vixed bar on the EAGLE3, then, by mounting the SMALL GP clamp

on the DUAL DEC adapter that comes with the M-zero obs (so you don't need to purchased it separately), it will be possible to attach this product on the lower side of the M-zero DEC arm.
Best regards
