Answer 1

I don't have a ready made sample for your but here is a good starting sample to iterate all subsite: Most efficient way to get all sub sites under a site collection/sub site using JSOM?

Try extending the script at after "var web = webs.getItemAtIndex(i);" to query the site for it's lists and include in the load whether the list HasUniquePermissions en the Roleassignments.

Please check below sample code for get permission of current user in particular list.

function checkPermissions() {
    var call = jQuery.ajax({
        url: _spPageContextInfo.webAbsoluteUrl +
            "/_api/Web/Lists/GetByTitle('Test')/effectiveBasePermissions",
        type: "GET",
        dataType: "json",
        headers: {
            Accept: "application/json;odata=verbose"
        }
    });

call.done(function (data, textStatus, jqXHR) {
    var manageListsPerms = new SP.BasePermissions();
    manageListsPerms.initPropertiesFromJson(data.d.EffectiveBasePermissions);

    var manageLists = manageListsPerms.has(SP.PermissionKind.ApproveItems);

    var message = jQuery("#message");
    message.text("Approve ListItem: " + manageLists);
});

}
