Oracle Exp/Imp Utility

If i do a full export from on database instance and import to a new instance, will that import the entire data and create tablespaces and users into to the instance?

Nobody, really has addressed your question in a proper manner.
If i do a full export from on database instance and import to a new instance, will that import the entire data and create tablespaces and users into to the instance?
Yes ideally it should & it will !!!
But there are few things that take it away from the ideal scenario.
When you take export of a database, it creates a dmp file and that contains all the information to create the same database...like information to create tablespace, users, db links, procedure...blah blah....
But...there are few things that need some attention.
One thing is tablespaces: That dmp file contains the SQL statements to create all the tablespacs in the database. It also includes the exact path of datafiles. Lets say my database A is on Machine1 and datafiles lie in c:\oracle\DB_A\*.dbf. Now when I run the import (in different database, on same or different machine) it will try to create the tablespaces with datafiles with the same name & on the same location as in database A. But that wont be possible in the case if you are importing to the database which is created on the same machine. Why ? As obviously you will have to keep the datafiles in different directory.
But if its on different machine, then its possible to use the same path for datafiles. But again be warned ! those directories should exist before you run the import.
Second thing is db links: For a db link to work you need to have entry of remote database in the tnsnames.ora file. If you are on the same machine and using the same ORACLE_HOME, you are done.
But with "different ORACLE_HOME on same machine" or different machine, you will need to make the entry of all the remote database [being used in DB Links] in the tnsnames.ora file.
Just few points, I have summed up. Might be I have missed something that may come up as an issue.
