>File > Open that displays a dialog box to choose the form to open.
>All data manipulation (Add/Delete/Previous/Next, etc) are on the form and on the Data menu (the word record doesn't mean anything to the typical user). Windows guidelines say everything should be accessable via mouse and menu. I am redesigning my framework and will move the buttons from the form to a toolbar.

We have debated the location of the buttons for some years here, and I still opt for the form + menu rather than toolbar + menu for nav buttons, for a couple reasons:

1) Particularly the Next/Previous buttons requires "focus" capability, since despite having search & sort features, our users typically need to scroll through record by record, often only browsing & making no edits. Thus, such buttons cannot effectively be on the toolbar, since they need to get and maintain focus for use with the Enter key. The shortcut key technique just isn't a popular substitute method.

2) There's no more space on the toolbar in some apps.

But I don't think there's any real standard for record nav buttons, in a different app with different usage I might use the toolbar also...
