The best place to find up to date certification information is under the Certifications tab in My Oracle Support. Search for Enterprise Manager Base Platform - OMS 220.127.116.11.0 and you'll get a list of all supported targets.
OBIA isnt listed specifically, but as long as the underlying OBIEE components are certified you should be fine.
OBIEE 10.1.3.4.1 (incl DAC) and IAS 10.1.3.5.0 are certified, so everything on your list except Informatica should be covered.
There isnt an Informatica target in EM, but you might be able to use metric extensions and service tests to cover your use cases.
