Congratulations on your new LA. I have a Gammill Vision and love it. You might want to check and see if your machine already comes with any of those accessories before ordering them. Mine did come with zippered leaders (and an extra set that I've never taken out of the bag), the extended base (a must for ruler work) and GamGuide Jr. (hated it, found it hard to use). The maintenance kit sounds like a good idea. Have to admit that, in 5 years and 150 hours of use, I have never needed any of those items replaced but, if you need one on a Saturday night, it would save you tons of frustration. Castors only have come in handy when needing to move the table to replace the carpeting. I think the micro-drive handles would be great if you expect to do a lot of small background fillers. Not sure what panto handles are. Mine already has handles on both the front and the back of the machine - maybe that's not standard any more.
