IR photography questions

[italy74]

Hi guys

although I'd have liked to get an ILFORD SFX 200, kind of b/w I used sometimes in the past that likes a lot to a girl whose wedding is on Dec. 31th, I could try some infrared roll as well, because the SFX is actually not available.

My lenses are: Nikon 17-35 - 50 F/1.4 AF - 70-200 F/2.8 - 105 F/2.5 AI and 200 F/4 AIS plus Tamron 28-75 and 90 plus CV 40 F/2

Just a hint: the wedding will take place since 18:30 onwards (even if I guess I'll be at bride's home 2 h earlier) and most of our shots could be done during night outside. Might it be a nice opportunity to try? I think I'll have to use the FM3a since the F6 uses an infrared sensor that might trick the exposure and/or do some other unpredictable thing to the roll.

A few questions:
1) how can I meter infrared light? same as always or such rolls have "different" metering from standard ones?
2) I doubt to have any IR mark on my lenses, although I think to have to focus FARTHER (?) than the effective focus point?
3) which kind of result might I expect shooting during night?
3b) What happens if I use flash?
4) which advice would you give me? Oh, yes, one more question: is it possible to SCAN IR rolls or they become damaged somehow? (I mean, aside having printed pictures, can I also scan them to show you?)

whatever comes to your mind will be greatly appreciated.
Keep in mind I'll shoot mostly with D700 and F6 but I'd like to try some IR pictures if I have time.

TIA

EDIT: I see Bjorn rates 5 for 17-35 and 105 (I have to get it back since just today I took it to repair, since after F/5.6 the diaphragm doesnt close) while both 200 and 50 aren't that good and 70-200 isn't mentioned either. Any idea for the CV40 and the Tamron 28-75 / 90 mm? Have you ever used for such pictures ?
