What is the best way to set-up my Database?

I want to revisit a few things posted in another thread I started a while 
back. Any help from anyone is appreciated.

I have a main form "Suspects" and a subform "sfrmBolo". The "Suspects"
form 
is bound to the Suspects table and the subform is bound to the Bolo table.

The Suspect table contains details about a person involved in an incident,

while the Bolo subform contains incident details. The Bolo subform is on a

tab on the main form. The top of the main form contains person details. I 
also have tabs for vehicle info, a physical description, and contact
history.

One of the pices of information on the Bolo subform is the name of the 
Petitioner (details below) which is my main reason for posting.

I also would like to know the best way to do the "Contact History" tab. It

would need to be a listing of all records associated with that person that
we 
could click and get details of that event (Bolo?)

"There are multiple ways to interface SuspectID and PetitionerID without 
having to show the AutoNumber values. One way is to use a combo box, where

the RowSource is something like this:
    SELECT PetitionerID, Surname & ", " + Firstname AS PetitionerName
    FROM tblPetitioner
    ORDER BY Surname, FirstName, PetitionerID;
Then set the first column to zero-width, so it stores the hidden 
PetitionerID value, but displays the name:
    Column Count      2
    Column Widths    0
    Bound Column     1 "

I now understand about the combo boxes you mentioned for PetitionerID. My 
first question is this: Do I need to make a separate table tblPetitioner?
If 
so, I assume it would need to have PetitionerID (PK Autonumber),
FirstName, 
LastName, PhoneNumber, Department ?

Assuming that table structure, Next question is: Do I need a separate form

to enter the Petitioner info? Would a sub-subform or subform be better?

Now, assuming it is set up this way, is it then correct to place a combo
box 
cboPetitioner bound to the PetitionerID PK field that does the query you
gave 
me earlier to combine the First and Last Name on the sfrmBolo subform? The

question is then, do I put the query "code" in the rowsource space on the 
combo options, and how do I make this combo a drop-down list? Let me 
clarify...if the petitioner does not exist in the list in the combo, I
want 
the add petitioner form to pop-up, so a new petitioner can be added. I do
not 
want the user to be able to just type a garbage name in the combo, since 
first and last names are in separate fields. I want to prevent user error
and 
confusion as much as possible.

Last thing is I assume after setting it up this way, I would merely need
to 
do a dlookup to pull the petitioner phone and department into the sfrmBolo

subform?

Am I on the right track?

Thanks for your help,
