Google Spreadsheets: How to get a first (Nth) row/column from a range? (built-in functions)

Question

Say I have this named range, not at A1.

      idz01  idz04  ida02
foo     a      1      b
bar     c      3      8
baz     8      2      g

N

Answer 1

Partial answer: (still open to better ones)

1st row

OFFSET(Data, 0 , 0, 1)

First column:

You simply can call some functions on the range and they take 1st column.
Or, if needed:

OFFSET(Data, 0, 0, MAX(ARRAYFORMULA(ROW(Data))), 1)

Nth row:
The key here is that OFFSET() only fills right and down. So you only need to crop these directions by it's parameters.

OFFSET(Data, N, 0, 1);

Could be also achieved by feeding the first row to ARRAYFORMULA() and for each column (cell), get the last row's cell using INDEX(COLUMN(),ROW() + N).

Nth column:

Similarly to above, only you need to get the number of rows.

OFFSET(Data, 0, N, ROWS(Data), 1);

I was playing with TRANSPOSE() but seems that OFFSET() doesn't digest it well.
