Oly c-4040, pt-010 housing

Hello,

I've just bought an Oly c-4040, a pt-010 housing and a Sea & Sea 90DX strobe. I haven't had the chance to use them yet and I wonder if you could give me some tips. First of all, I have problems with the velcro pattern of the strobe's fiber optic cable, it keeps moving and the strobe mask isn't completely attached to the tape of the housing. what am I doing wrong?....I also have a Fish eye tray and when it is attached to the camera I can't use the weight that makes it neutrally buoyant, does anyone have the same problem?

And finally I have some questions about using the OLY c-4040 underwater, what type of light metering should I use? and should I set the Full Time AF function or not?

What about the zoom? 35 mm, 55, 80 or 105 mm?

Lots of questions I know, sorry , but I'm new in this and you don't get those answers in the manual :-)

Thanks to all !!

A good answer to all these questions would take pages. Most of these issues have been discussed in this forum, some many times. Have a look at this one http://www.wetpixel.com/forum/viewthread.php?tid=450 for example, then use the search function on this site and see what you can learn on your own and try to narrow down your list of questions.
