For reading in data, normalizing and computing e.g., t-tests or F-tests
you can use either:

marray* packages or limma

For doing multiple comparisons corrections you can use either

multtest or siggenes or limma

You can also use combinations of the above, but for starters it might
be easier to stick with one paradigm until you get up to speed. Best
idea is to have a look at the vignettes for these packages and see which
one looks good for you.
