I think I over-repotted... help?

[AnitadeWaard]

Hi all, fairly new to orchids but completely smitten. In my newbie enthusiasm, however, I think I have over-repotted e.g. my Miltassia (Lavender Kiss, Lavender Taffy) and a Cattleya (Blc. Lawless Zauberflotte Palmer's Orange)! They weren't doing great (miltassia's leaves started to yellow, (fig 1 and 2) and Cattleya was looking peakish (fig 4, no new growth etc.) so I was worried I had over-watered them and repotted them (Miltassia to a pot instead of a basket (fig 3) and Plc to a basket instead of a pot (fig 5)!). But now I worry (again) that I over-repotted them: pics enclosed of the plants, the roots, and the new situation.... Anything I can do at this point, except let the poor plants a rest from my overzealous activities? Should I feed/water/more or less... ? Thank you for any insights!
