Phalaenopsis Orchid with a Mealybug infestation

[SMcNece]

I would call myself an experienced novice orchid owner .. but I am really unprepared for what's going on with my plant. My husband bought me an orchid from a nursery about 3 weeks ago, and it's developed a mealybug infestation (determined thru careful research on the internet and this site) I carefully swabbed all of the plant that I could see with isopropyl alcohol and I read that I need to re-pot the plant, what steps do I need to take in the repotting process that will prevent further infestation. Also I have another orchid that sits quite close to the new one that doesn't show signs of infestation (I've been monitoring it very carefully) should I re-pot that one as well? The local nursery that he bought the plant from doesn't carry any items other than orchid bark for the care of the plants, I've ordered all new items to replace everything with the plant currently, including stakes and clips and plan on washing the decorative pot with a bleach mixture and allowing it to dry before using it again.

Any information would be helpful! Thanks!
