Did you use oblique because you thought that the factors should be correlated?
If so thats ok. If you thought that they should be independent then you
should use
varimax.

Forget communality scores report eigenvalues % of variance by factor and
factor loadings above .4 or .5
Be careful when using any rotation method. You will need to recalulate the
eigenvalues and thus the percentage of variance accounted for by each
factor. Do this by squaring the loadings on each factor and sum them up.
You can then realloacte the % of variance for each factor on a prorata basis.
Look at previous issues of the journal but as I indicated I do not think
that communalities are necessary. Read the SPSS user guides for info on the
significance of communalities.
