If you are  Using Components as Boilerplates it will apply at global level only. Recheck the resourceType path as documented athttp://dev.day.com/docs/en/cq/current/developing/boilerplates.html

The cause of the replication error is the absence of the jcr:content node under the items page, Please try to delete the items node on the publishers directly via CRX Explorer or CRXDE Lite (it will delete also the sub-pages), and then to use tree-activate function of /content/mobile/en/company/navi...

When upload initiates you would see in logs [1].   What usecase you are trying to address?[1]  POST /content/dam.createasset.html

It gets a ValueMap from a Resource[1]. Check for optionsLoadPath if true adopt the return into string array. Otherwise get default values from options properties.[1]   http://dev.day.com/docs/en/cq/current/javadoc/org/apache/sling/api/resource/ResourceUtil.html

The property rep:disabled is set on an authorizable node (rep:User or rep:Group) that user or group becomes disabled. However this property is protected and you cannot set it directly.Though I am not sure is security API provide that option. You can try with User.setProperty().

AFAIK servercaches list all cached LiveCopies & ideally be used for debugging. It should be deprecated. Rather than document fix it should be removed.  For now the workaround as you mentioned to make curl request or restart the msm bundle.

Still not clear. TO begin with start from http://helpx.adobe.com/experience-manager/using/using-sling-apis.html

Your post is very high level. Could you please explicitly specify what exact sample you are looking.
