Hi skimmer
To cut to the chase - I had both ventouse and forceps as my DS was arm and head presentation (arm tucked behind his head) and I had been pushing for 6 hours. It wasn't that dreadful as I was relieved the doctor was going to get 'the baby' out and that it would be over quickly. Like others have said, you really don't care by that point.
I had an episiotomy and a lot of stiches afterwards in theatre while my DH held our son outside. I felt a bit envious of this at first but it was a very special time for him (DH) and we were given time to be the three of us before I was taken into theatre.
My DS was beautiful, clean, not stressed, slightly long head which went in a day (but I think they tend to have that anyway). He had 2 scratches on the side of his face from the forceps which disappeared within a few days. He did have a nasty blister on the back of his head from the ventouse which had gone by 10 days (babies heal amazingly quickly).
I'm afraid I haven't read all of this thread so I may be repeating what others have said. I think the best thing to do is make a birth plan but be open-minded and make sure your DP knows what is in it too. In the end I was saying 'yes' to things I had been adamant I wouldn't have done but you have to have faith in the midwives and doctors.
My DS was absolutely fine following his birth. We did take him to a cranial osteopath to get him checked out but he hadn't suffered any ill effects. He was a good feeder and a fantastic sleeper.
Try not to worry. Most women find childbirth tough but the end result is amazing. 5 minutes before my DS arrived I was really upset (although I couldn't express it) that 'it' was going to be an only child. 5 minutes after he arrived, I knew he could have siblings! It's not always that quick but most women do have more than one!
I hope your birth is easier but ultimately it is the most fantastic experience. Enjoy your last few weeks and good luck for the big day.
