Maybe I'm not the right person to give you advice because I just tried the T i was referred to from my first T (who I hadn't clicked with as she felt judgemental and was never on my side) and I was really lucky. I see how difficult it can be to find a good match, so I'd say, definitely meet all of them unless you decide you really like the first or the second you see. I would mention the current T face to face with them as they might be willing to talk about it for a while but that's just my opinion - and I think the email is ok.
About the skills, maybe go for those who seem to have what you need first, but just in case you aren't sure about any of them, don't hesitate to see someone else if something about them inspires you (don't know, photo, short presentation on website etc..). I'm saying this because my T is very young and doesn't specialize in ed and my other issue yet and I was skeptical. But I'm healing and I only want her with me in this journey now, because she understands me like no one else while the previous skilled, very experienced T was a nightmare to me.
Sorry for my English and... good luck, let us know how it goes
