Solução

In addition to webdad3's answer.

Private Sub Form1_KeyDown(ByVal sender as Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown

    Dim tb as TextBox = TryCast(me.ActiveControl, TextBox)
    If tb IsNot Nothing Then

        Select Vase e.KeyCode
            Vase Keys.Right, Keys.Left
                dim forward as boolean = e.KeyCode = Keys.Right
                me.SelectNextControl(Me, forward, True, True, true)            
                e.Handled = true
        End Select

    End If

End Sub

Don't forget to set Form.KeyPreview to true (via Forms Designer)

For the second part:

There are many, many different ways to format the text of a textbox. The best solution would be to use DataBindings (complex topic, read a book about it.)

Public Class Form1

    Public Property Price as Decimal

    ' call this code once
    Private Sub InitControls()

        Price = 3.45

        me.txtPrice.DataBindings.Add(
            "Text", Me, "Price", True, 
             DataSourceUpdateMode.OnPropertyChanged, Nothing, "0.00"
        )

    End Sub        

End Class

End Sub
