PST Stage 1 + AR152, AR102, 72ED etc. next steps ...

ADDITION - I failed to mention I will use the Altair 178M camera I am already using with PST
Hi again!
Sorry for being 'slow' and possibly thick.
My plan:
1.
I think, first thing is to get the 2" adaptor for PST - so I am ready to play with Stage 1 [I guess it is called?]
2.
Then get a 100mm ERF [when i can afford it] and make an adaptor/cap myself - I am good at it [or so I believe!] and fit 3x Nylon screws on it to hold it in place, behind the edge for the retractor's shield.
Although I am now thinking I should take the shield off for Solar, so the ERF is next to the glass?
3.
Then fit the 100mm ERF over the AR152 [988mm FL - 152mm Diam - F/6.5] - so it becomes ~F/10
4.
Then eventually also test my AR102SX [459mm FL - F/4.5] and make a 45mm 'card-board' reducer covered in tin-foil 'over the 100mm ERF' and reach F/10 again
5.
For full disk I can use my SW 72ED and simply adapt the 100mm ERF cap over the SW 72ED - maybe just fit longer nylon screws to hold it!
I might have to keep those cream cheese card-board round boxes then (~110mm diam)!!!
6.
or simply get a 63/840 OTA and there is no need to get a ERF (although always best to get one!)
My questions:
a.
What are your 'expert' thoughts above my points above?
b.
Where am I going wrong in terms of 'being able to focus easily'?
c.
Please tell me I am thick, but give us a solution that can account for:
Results [first], Focusing and costs ?
I am no expert and cannot contribute much 'at least at this stage'
Thanks again for taking the trouble to reply.

PS I am a kind of practical guy and 'do this and do that' replies are the best to achieve ... at least with my brain ... I usually learn by watching others and as a friend of my late dad used to say: I might be no expert in something and it might take 5x the time an expert takes to do it, but I will blooming do it too! I take this approach too, but do a lot of research first and learn from others than know FAR more than me.
First you learn what I am going to do that, then the how to do that becomes easier knowing what you are doing.
