Spot any issues with this mini Phalenopsis

Others have addressed your concerns about repotting and possible pests, so I'll just say, regarding your concerns about the scars on some of the leaves, I see nothing at all to be worried about. Stuff like that happens when mass quantities of orchids are being moved during their long journey from commercial nursery to retail store. It's just cosmetic, and as the plant grows and sheds it's lower leaves over the next few years, those scars will be gone.

Last year, I bought one with leaves that looked worse than yours, just because I loved the color of the flowers. It's thriving.

Also, FWIW, I grow Phals in a house that sounds like it has similar temps and humidity as yours, and they do very well. I use a chunky bark medium (Orchiata), which allows for air to reach the roots, so nothing stays wet too long, but the flip side is I have to water frequently, maybe more often than some would have the time or patience for, but I only have a small number of plants, so I don't mind.
