AutoCAD LSP; delete unused layers and rename layer

[KKraus]

In a nutshell, I'm trying to create an LSP that will
1) erase all unused/frozen layers
2) create a new layer call CUTOUTS
3) Color this layer Red.

Issues:
1) LSP is only erasing both hidden and frozen layers if a frozen layer is present to initiate this routine.
2) Works well, but i'd like it to make everything displayed to also be put onto this new layer
3) The xref layer is red but the 'object' layer remains white. (i can explain further if needed)

My code thus far:


(defun c:KK (/ ActDoc LayList LayNameList)
;; Erases all objects on frozen/off layers, then purges drawing.

(vl-load-COM)

(setq ActDoc (vla-get-ActiveDocument (vlax-get-Acad-Object)))
(vlax-for Lay (vla-get-Layers ActDoc)
(if
(or
(= (vla-get-LayerOn Lay) ':vlax-false)
(= (vla-get-Freeze Lay) ':vlax-true)
)
(progn
(vla-put-Lock Lay :vlax-false)
(setq LayList (cons Lay LayList)
LayNameList (cons (vla-get-Name Lay) LayNameList)
)
)
)
)

(vla-StartUndoMark ActDoc)
(if LayList
(progn
(vlax-for Layout (vla-get-Layouts ActDoc)
(vlax-for Obj (vla-get-Block Layout)
(if (member (vla-get-Layer Obj) LayNameList)
(vla-Delete Obj)
)
)
)
(vla-PurgeAll ActDoc)
)
)
(vla-EndUndoMark ActDoc)
