Matrix - Need Data Sorted Into Lists

I have a matrix of mixed numbers (going across many columns and rows) in Sheet1. They are a mix of positive and negative numbers, In Sheet2 I need 2 lists to be automatically displayed, taken from the data in Sheet1.

The first list (column) is for positive numbers only, the second is for negative numbers.

There is one filter: only numbers over a specified value (for the positive list) must be used from the data, and only numbers under a specified value (for the negative list) must be used from the data. The 2 filters can be stored in any cells in Sheet2 (the worksheet where the lists will be), lets say, for ease of use, A1 and B1.

But here's the tricky part: I need the location reference of each number in the matrix displayed next to the number in the list!!! Eg: in the matrix, I have names running down the left (A2 to A25) and the same names in the same order running across the top (B1 to Y1) - just like any basic matrix! If A6 is called "John" and L1 is called "Pete" and their value (at cell L6) is 10, then I need them to be displayed in the "positive list" amongst the others (sorted automatically into numerical order) with the words "John" in the cell to the right of the score, and "Pete" in the one after that to the right: so it will look like:

A2 B2 C2
10 John Pete

(remember that these 2 lists are on Sheet2, not on the matrix worsheet! A1 and B1 contain the 2 filters for the positive and negative lists).

Of course, this must only happen if the filter in A1 (the positive filter) is 10 or under. If it was anything above 10, then this one would not make the list.

As for duplicates in the matrix coming up twice in the lists, that's not a problem this wont matter! It's ok for the lists to have constant duplicates displayed eg: 10 John Pete will also have next to it 10 Pete John.
