Connectivity for iPad Pro to monitor/projector

I am an educator who needs to be able to to connect an iPadPro to screen projectors, both through HDMI and VGA. Ideally, I'd also like to be able to use a wireless presenter / laser pointer if possible. I already own a Logitech Professional Presenter R800 (with green laser / wireless connect via a usb hub), and would prefer to use it.

Question 1:

Is there any hub / connector which would accomplish all of this? (or at least an HDMI / USB combo)

If there is not a solution to Q1, then 2 separate follow-up questions ...

Question 2:

then would the following solution work for connectivity for HDMI/VGA?

Apple Lightning Digital AV adapter MD826AM / A (for HDMI connectivity) (there seem to be very mixed reviews on this connector though)

plus

some type of HDMI to VGA connector, such as:

or http://www.amazon.com/Tendak-Gold-Plated-Converter-Adapter-Projector/dp/B00VTJVJ 3S/ref=sr_1_4?s=pc&ie=UTF8&qid=145377276…

Question 3

and for slide changing do either of the following compatible work with the iPadPro?

(1) Satechi Bluetooth Smart Pointer Mobile Presenter (but, no laser)

(2) Kensington K39524US Presentair Bluetooth Presenter/Laser/Stylus (but, red laser)

(3) something else?

Thanks in advance
