Drawing PCA

#1
After doing factor analysis in SPSS, I have got a component matrix showing 6 components on the top row and all variables on the leftmost column. How can I view the PCA plot/graph now??
Thanks

For doing PCA is it true that the number of variables should be equal to or less than the number of individuals and that at least three variables for each of the components/factors should be included? Kindly post the link if any web-literature is available in this regard.
Thanks
