BC4J Custom Type Maps (MS-SQL cont.)

Question

(FYI using JDeveloper 9.0.2.0.0, MS-SQL 2000 spk2 and MS-SQL's JDBC driver Version 2.2.0022)
In the process of trying to get JDeveloper working fully with MS-SQL, I am at the point of developing a custom type map.
Should this typemap include all mappings or only those different than the "Java" or "Oracle" type map? I was assuming all at first. Now I wonder how it's handling missing mappings.
How does it find a matching typemap? I noticed that Entity's database column types looked like "int(10,0)" and "bit(1,0)", but in my typemap, like the examples, it's just "INT", "BIT" with no precision, scale. Is this a case of where it's assuming the driver will return a string for type and it's returning type(p,s)? Or is JDev building that string? Either way, would you need a different mapping for "bit(1,0)" than "bit"?
As "bit(1,0)" it had problems with both the Java map and my custom map. Changing it to "bit" seem to get it to work. So what typemapping was it trying to use as "bit(1,0)"?
[Bug?] I noticed that when I view the bc4j settings (project (rt-click) -> edit business components project), the value for type map is incorrect if I am using a custom type map. If I am using the Java type map it says "Java" in the greyed out select, but if I am using my custom map ("MS-SQL"), it says "Oracle". I checked the bc4j.xcfg for the one using my custom map and it does say the right class name for jbo.TypeMapEntries.
On a related note, when testing the bc4j modules, we are instructed to use the edited local configuration, but how do view/edit the project default configuration?
