How to effectively drill (1)3 permanent retainers (EZSV)(2) a PosiTrieve packer

The wells were drilled in the late 80's.
(1)In the first, after each test, a permanent retainer was set and the next zone tested. Now we wish to open the whole zone. I have had prior experience trying to drill one retainer on top of another and it was difficult due to 'spinning'.
(2)The well was abandoned with a cement plug and PosiTrieve packer above the zone of interest. We don't expect any problems with the plug but anticipate having to drill the top slips and push the packer to bottom. I should add that attempts were made to pull/fish the packer previously without success.
Has anyone else developed any specific techniques for either of these circumstances?

Thanks
