Now you're Stalking! Mystery Cache

The questions:

A On a business trip to Glasgow in 2009 Mr BH found a cache whose name was a lady’s name. Add up the numerals in the GC code of this cache. If your answer is 10 or more, add up the digits of the answer until you arrive at a one-digit number.
(Incidentally, once you’ve identified the cache concerned, have a read of the story recounted on the cache page, It’s most interesting.)

B What is the highest number of Letterbox caches we’ve found in one day?

C Nearly two years ago (at time of placing) we found a much-loved cache whose name implied a certain number of wooden objects. How many?

D The very day we registered our Geocaching account, another cache was being hidden, which we went on to find 17 months or so later. What is the last numeral in the cache hider’s name?

E One of our favourite types of caches is the Church Micro. But we've found a number of church caches (by which I mean caches that have the letters 'church' consecutively in the name, including as part of a larger word) that are not Church micros. How many? (final digit of your answer, add 1)
(NB there are some borderline cases in our finds, for simplicity if you see the words 'church', 'micro', and a number in the cache title, for these purposes it's a church micro.)

F & G On a trip to London in May 2011 Mr BH found a cache whose name contained differing numbers. What were they? (numbers in order) NB You're looking for two distinct numbers and not a two-digit number.

H On another trip to London we were able to find 7 different types of cache in one day. In chronological order that day, in what order did we find the letterbox cache?
(NB we are talking about distinct cache types rather than cache finds, for example we found several different traditional caches. Basically, disregard any cache after the first cache of that type we found that day for the purposes of this question, you are only considering the 7 caches of seven different types.)
Which day was this? Well you can work out for yourselves…

I We have found three caches with exactly the same co-ords. Although we found them on different days, two of the three were eligible to be logged on the same day. Work out which day of the month the first of these was placed (chronologically).

J How many smileys did we log on the second International Geocaching Day?

K On 16th April 2011 we walked round a trail hidden by a much-celebrated cacher, and good friend of ours. But which numbered cache did we like so much we gave a favourite point to it?

L On the weekend that Geocaching celebrated its 10th anniversary we hit a milestone of our own. How many hundreds of caches did we get to on that weekend?
