I'm very new to Meteor and looking to start my new project in it as the system looks great.
Before I commit myself and dive straight in to code, I have a few queries about whether some planned features are possible with MeteorJS.
I realise that there is Telescope which would make this for me, but I want to learn the language from the ground up and not just have a plugin in create everything for me.
All of the functionality you are looking for is possible with Meteor. If you really want to learn meteor take a look at this reddit thread. My personal choice is eventedmind.com I found that, for me, the material is easy to understand and very in depth, it gives me a solid understanding of the Meteor system not just fast prototyping/scaffolding. I also purchased the Discover Meteor book and found it to be rich and informative.
I highly recommend taking a close look at meteor, it amazing!
