UDM template and Notification Rules

Question

Hi,
As i am first time working with EM grid control have few question upon organizing some things for better feasibility. I am familiar with the creation of a UDM template and creating notification rules. But I am lacking in proper organization of these thing. I have been provided the events (customized) categorized say security, performance, etc. So i have created a UDM for these events separately for testing. So to create template, how shall i proceed, is there any standard process or anything that would be helpful in all means.
I was having different ways, like as i already created UDM's
(1) create template for each event (UDM and out-of-box),
(2) create template for events by category (UDM and out-of-box) ,
(3) Create one standard template for all the UDM's and out-of-box events ,
(4) Create templates based on OS UDM , SQl UDM and outof box metric events.
(5) Create templates based on Host and database events.
these are of few different way in which i am having in my mind. But not sure of feasibility solution.
Also if am not wrong templates are only for applying to targets and they are not related w.r.t notification. So w.r.t notification I would like to know is that it would be better to categorize them with in default rules or make separate rules.
Sorry for such series of question.
Thanks.

Thanks Rob. I came across one more thing while i am working with metrics. I see the metrics and policy settings pages differs w.r.t database version's,
Say for example, with in 11g database metrics and policy settings i see following metrics,
(1) Access Violation and (2) Access Violation Status, but i dont see these in 10g version database metrics and policy settings page. In 10g i see Following metrics
(3) Active Sessions Waiting: I/O and (4) Active Sessions Waiting: Other which i see in 11g version database metrics and policy settings page but can't see on 9i
version database metrics and policy settings page.
So under such circumstances if i create a template w.r.t target type say database, that would have only the selected version while creating the database. Is that like do we need to create template for each database instance ?
As i see we have an option of including the metrics present in another database version too, but if we add those into one what would be result as few metrics one instance is not aware of and also i see one situation where in one of the metrics to check for the database instance status differs from 9i and 10G ( i mean the naming conventions) In this case if i add both , we are going to get an alert twice as i presume. How to handle such situations while creating a standard template.
Please advise if this need to be created w.r.t target type how to create it. Is that we can create w.r.t each version of database instanc target type too.
Thanks.
