getResources generates the list of items. getPage only provides the pagination, breaking your list up into sections and providing the prev/next or numbering controls. So forget about getPage until getResources makes the list you want. Then put the properties from that getResources call into the getPage snippet call.
Consider the runSnippet() function. It takes two arguments, the name of the snippet to run, and an array of properties to pass on to the snippet. For example,
runSnippet('getResources', array('parents'=>8, 'tpl'=>'myTplChunk');
Basically that is what getPage is doing internally. That means that you have to give getPage all of the properties you want the getResources snippet to have, because getPage has to pass them on to its getResources snippet call.
The paging properties listed on the getPage documentation apply to getPage itself only. They have no bearing on how the internal listing snippet gets run. You have to supply the properties needed by that listing snippet.
