Capture of synonyms from existing online oracle9i database

Question

Hello!
I am a newbee in oracle designer .I need to Design capture the ERP application into designer repository.The story goes like this ::
I am in a scenario where an ERP Application is running but without any documentation and configuration control.The Application is developed using Oracle10g Forms developer and reports,with backend oracle9i.The application and so database contains a lot of user schemas corresponding to the functional departments of organisation like finance , inventory.
I have successfully Installed the repository (version control option enabled) on our online database('oratest') and created a repository owner 'desg',with DBA Priveleges.
I have also created a database definition named 'oratest1' and a user named 'desg1' in the design editor's[b] System folder..
I tried to capture the schemas in following sequence (using the option - Generate/Capture designof/servermodel). ::
a. Login as Desg , Owner = sys-- Captured all tablespaces
b. Login as Desg , Owner = desg-- Tried capturing designer objects but was not very successful
c. Login as Desg , Owner = sys-- Tried capturing all sys objects , It took a lot of time with error and warnings and I was only able to capture some tables and views.I also tried with owner = 'System'.
d Login as Desg , Owner = sys-- Captured all users from oratest to oratest1(errors displayed 'Invalid grants ')
e. Login as Desg , Owner = sys-- Captured all roles from oratest to oratest1(errors displayed 'Invalid grants to user objects')
f. Login as Desg , Owner = User schema1(say inventory) -- tried to capture relational tables,views,functions,procedures etc. A lot of errors saying that invalid references to objects i.e referenced objects not present in the repository.
g. Noted down all dependencies using the DBA Views to user schema1 and captured corresponding objects from database into corresponding users in the repository.
h. Login as Desg , Owner = User schema1(say inventory) -- Again tried to capture objects of this schema.It gives error that ' Cannot capture synonyms with same name as objects name, either recreate or make all of them public'.
Following are my queries for which I need all your expert help::
1. First of all ,is the sequence in procedure above alright ?.Is it necessary to capture 'SYS' , 'SYSTEM' Objects ..What if I have already done so,will it cause damage? If so is it is possible to remove them from repository automatically?.I captured since the user schemas refer to these objects at several places.
2. Is it required to capture different User Schemas into different containers or just a single container ? If it is required to capture in different containers , how will tablespaces,users and roles already captured into system folder refer to objects in these containers.
3.Regarding problem of grants : When are the 'grants' be captured,before the capturing the objects or after them or anytime.Is it required to capture grants via a DDL file . Will a text file generated by export grants option in 'Toad' tool will do the job?.
4. Regarding Problem of capture of synonyms :: In most of user schemas , the private synonym has same name as the object which it refers.Hence designer is unable to capture the synonyms.If we make Synonyms public for a user schema than what about other schemas?. Secondly how to capture synonyms independently.Is it via a DDL File.Where in the design editor can we see the captured Synonyms?.How Shall we capture Public synonyms of our ERP application.
5.In the server mode tab, under relational table definition,I can see all the mixture of user tables and sys tables.How can we isolate the tables as per user schemas and generate Server model Diagrams for individual schemas.
Please help to resolve these Issues.
Thanks
With best regards

Thanks For your reply.
I am successful in capturing all other objects of the schema.
Before Your reply and before capturing other objects, I tried to capture the private synonyms by first creating a ddl file and than modifying the SQL 's 'create synonym' statements to 'create public synonym', and than captured the public synonyms into the repository via design editor. In short I captured the private synonyms as public into the repository.It gave 0 error and 0 warnings.
But where in the navigator pane can i see the captured synonyms. I cannot see any of them, so iam not sure whether they are captured or not.
After this when I captured other objects , they were captured successfully without any errors.
