If you only knew how large your horizon is with the RB....:-))
There are roughly 4 films on the market today, ranging from real-IR 
to pseudo-IR (Kodak HIE/EIR, Konica 750 IR and Ilford SFX200 & Agfa 
APX200S). 
While all these emulsions are available in 35mm, only Konica and 
Ilford (recently) are available in 120. Yet Kodak HIE/EIR *is* 
available in medium format, 70mm perforated.
And the magic is that Mamiya makes just such a back for the RB, since 
the days of the Pro-S (with all the necessary interlocks). 55-65 
shots from one roll/cartridge, a neat feature even with other 
ordinary films (see my homepage for a full list of 70mm emulsions, 
URL below in the admin footer).

Btw, I currently have a line on two new RB backs, for 
US$400 each. That's about half the new price....
In box, with manual. If anyone is interested, send me a private mail.

> 2. Which films to learn with.

I would select films on their image effect....doesn't make much
sense to learn the entire chain of image taking to final print with
a film you won't use later on anyway. The strongest
romantic/dreamy/otherworldly effects can only be obtained with Kodak
HIE and a dark IR filter....

> 3. How to focus

Depends on your lens.
PS: Mamiya makes drooling APO lenses with which no focus correction is 
necessary....;-))

> 4. Filters needed

Depends on what image effect you want, and how low the exposure index 
is you can deal with. Kodak HIE & #87C results in an effective 12 
ASA.

No. Only applies to Kodak HIE, but the felt trap is not IR-proof, and 
even it were, light would find its way in by means of light piping, 
as HIE doesn't have an antihalation layer.

For more info about IR I recommend you read the IR-FAQ first (which
you should have done if you had read the welcome message from
Majordome carefully....;-)). A link to this FAQ is on my homepage,
