Hi lisalou,
If you want I have a really good article all about molar treatment that I can send you. Tried just now by MN says you are "uncontactable" settings? Its got much more in it than you will find on the internet. I was sent it by a doctor at Charing Cross.
I think it will reassure you a bit because your numbers sound really good. Lots of women start out at 10 or 20,000! I think when your numbers are low and dropping fast you are very likely to get the all clear to ttc quicker. (dont want to get your hopes up but some women only have to wait 3 months in the end.)
I think it helps to get as much info as possible, I went beserk on the internet looking at everything, like you I had never heard of it and I was so scared because I was abroad. I think it helps a lot to make all your family read stuff too. They must be scared for you as well.
My numbers went 292, 50, 9, then 0 (or rather not dectable, as less than 5 is not detectable) The scary bit for me was that I was sent for xrays on the day I was told, and they found a lump on my lung. Everybody thought it had spread in a cancerous way already (it had been two months since my miscarriage) I had an ERPC at that point and when they examined the tissues they told me it WASNT molar. (but placental cells had regrown after the miscarriage) I still have to get the lump on my lung checked out - looks like it was a red herring, hopefully its nothing serious. Its hard not knowing what really happened. At least when it was partial molar diagnosis I knew I could get it treated.
As far as ttc again, I am waiting for my first AF and then I can start, but to be honest, now that the physical stuff is calming down I am only just beginning to deal with the loss emotionally. I am not sure if I am really ready yet. My first reaction, like yours was just to replace the baby I'd lost as quickly as possible. (and to you it was a baby, you had no idea this wasnt a normal pregnancy) But I think you really do need some time to accept the loss first, and any pregnancy you start will be a new thing entirely. Take the time to grieve and say goodbye 
If you did get pregnant again and worried about another molar you could always ask for your HCG to be monitered in the early weeks. If it doubles every two days its normal pregnancy, if it goes higher it is a sign of a mole. These tests arent done rountinely though, so most women wouldnt know unless it shows up on a 10+ scan.
Anyway, better stop, I have written a book! (and very therapeutic it has been too!)
Hopefully you only have one or two tests to go until 0. Fingers crossed for you.
keep me posted
