I would suggest making all of these items related via numeric IDs, you then
dispose with having to traverse up and back down the DOM to find the related
elements:
<tr>
<td>
<select id="select_1">...</select>
</td>
<td>
<input id="text_1a" type="text" ... />
</td>
<td>
<input id="text_1b" type="text" ... />
</td>
<td>
<input id="text_1c" type="text" ... />
</td>
<td>
...
</td>
</tr>
// Update 2nd column <input> with new_value.
// $(this) is the select in the first row cell.
var index = /select_(\d+)/.exec(this.id)[1]; // Get the number from the
ID. There is no checking if it doesn't match.
var new_value = $(this).val();
$("text_"+index+"a").val(new_value);
Incidentally, as I've used here, the .val() function is a handy shortcut for
.attr("val", ...)
I don't know what the speed difference is here but I'm guessing it'll be
pretty good.

Depending on the select option I need to modify or clear values in the
text inputs in the 2nd, 3rd, and 4th cells.
I find that this code works, but suspect there may be a better way to
achieve the same result with less code?
// Update 2nd column <input> with new_value.
// $(this) is the select in the first row cell.
$
(this).parent('td').parent('tr').children('td').eq(1)children('input').attr("value",new_value);
Since I'll be updating various cells I suppose this helps, but again
suspect there is a better way.
var cells = $(this).parent('td').parent('tr').children('td');
cells.eq(1).children('input').attr("value",new_value_1);
cells.eq(3).children('input').attr("value",new_value_2);
cells.eq(4).children('input').attr("value",new_value_3);
Thanks
Brad
