How To Add Data Into A PK To FK Relationship?

Hi
I have 2 tables one is called QuickLinks and another called QuickLinkItems
QuickLinks
QuickLinkID<PK>        UserID                 QuickLinkName
--------------------------       -----------                ------------------------
1                         111-111-111-111            QuickLink1

2                        111-111-111-111             QuickLink2
3                        222-222-222-222             QuickLink1
 
QuickLinkItems
QuickLinkID <FK>          CharacterName           CharacterImagePath
---------------------- ------------------------------- ----------------------------------------
 1                                a                            path1
1                                b                            path2
2                               d                              path3
2                               e                              path4
3                               a                              path1
4                               b                             path 2
 
So thats how I see the data will look like in both of these tables the problem however I don't know how to write this into Ado.net code. Like I have made a PK to FK relationship on QuickLinkID(through the relationship builder thing).
 I am just not sure how to I do this. For the sake of an example say you have 5 text boxes 2 text boxes for inserting the character names and 2 text boxes for inserting the CharacterImagePath. Then one for the Name of the QuickLink. So how would this be done? Like if it was one table it would be just some Insert commands.
 Like if this was all one table I would first get the userID from the asp membership table then grab all the values from the textBoxes and insert them where they go to and the QuickLinkID would get filled automatically.
 
The thing that throws me off is the QuickLinkID since it needs to be the same ID as in the QuickLink table. So do I have to first insert some values into the QuickLink table then do a select on it and grab the ID then finally continue with the inserts Into the QuickLinkItems table? Or do I have to join these tables together?
Thanks
