Orion 9x50 Illuminated Right-Angle Correct Image Finder Scope Guiding?

[Aussie Dave]

G'day all, another week and another question from a beginner in AP.

I have an Orion 9x50 Illuminated Right-Angle Correct Image Finder Scope. I've been reading more today here on the stargazerslounge forum and from my understanding, I can use this finder scope as part of the tracking.

atm I have an older EQ4 mount with polar allignment scope. It does not have motorised tracking which is another thing I'm still looking in to. I have a few questions...

- What else would I need to buy for this setup? From what I can work out from the link below, an adapter and T thread guide camera (the first 2 products) ? http://www.modernastronomy.com/accessories.html

- Will this help with more accurate tracking for AP (once I get the motorised tracking mount)?

- Will this give me live view through a laptop?

All info greatly appreciated and what I need to buy next.
