Two groups & two

Hi

Wondering if anyone can help with this one. Well, several really.

I am planning to conduct a study examining how easy it is to use two different computer programmes that do the same thing. I am also planning to study each programme in two different groups of subjects (although matched for age etc).

The data I am planning to collect is as follows:
Able to complete the task (Y/N; nominal)
Time taken (sec; ratio)
Subjective opinion (Likert scale, 1-7, ordinal).

What I really need to know is how I analyse all these different types of data so that I can compare performance between the two groups separately on each programme and the performance within each group on each programme.

Any help really appreciated.

P.S. Sorry for the long message, hopefully you made it to the end. :)
