Hi,
The thing about using Lightning Data Service is that when we are using "force:hasRecordId", the component automatically fetches the recordID of record on whose layout it is on.
Q. Does "record id" included "record type"?
A. No, the record id only contains the recordID of the record but you can perform a SQOL to get the recordtype Id of that record.
Q.Can I skip targetRecord?
Can I just using targetFields?
A. Yes, you can skip the targetrecord, it works. But it isn't considered as a best practice.
targetRecord is populated with the loaded record.
targetFields is populated with the simplified view of the loaded record.
v.targetFields.Name is equivalent to v.targetRecord.fields.Name.value. Therefore for easy dereferencing of object properties we use v.targetfields.
Let me know if this helps.
Thanks!

Id sampleid = '00561000000Mjya'; System.debug('object is '+ sampleid.getsobjecttype());Through the record id, you can find the object and once you know the object name you can extract the fields .
