"How do I cange the Xticklabels of a plot using figure handles?"

Get the axis handle from the figure handle.

ax = gca(figureHandle); 

Get the XAxis handle from the axis handle and set the FontSize of the x-axis only.

ax.XAxis.FontSize = 16;

or set the fontsize of the entire axis (x & y)

ax.FontSize = 14; 

Set the XTick and XTick labels

ax.XTick = 1:4; 
ax.XTickLabel = {'A' 'B' 'C' 'D'};

There are xticklabels() and yticklabels() functions built-in. From the help:

xticklabels(labels) sets the x-axis tick labels for the current axes. Specify labels as a string array or a cell array of character vectors; for example, {'January','February','March'}. If you specify the labels, then the x-axis tick values and tick labels no longer update automatically based on changes to the axes.

Also, see my little demo that shows you how to change a bunch of things independently:

% Create sample data.
X = 1 : 20;
Y = rand(1, 20);
plot(X, Y, 'gs-', 'LineWidth', 2, 'MarkerSize', 10);
grid on;
title('Y vs. X', 'FontSize', 12);
% Make labels for the two axes.
xlabel('X Axis');
ylabel('Y axis');
% Get handle to current axes.
ax = gca
% This sets background color to black.
ax.Color = 'k'
ax.YColor = 'r';
% Make the x axis dark green.
darkGreen = [0, 0.6, 0];
ax.XColor = darkGreen;
% Make the grid color yellow.
ax.GridColor = 'y';
ax.GridAlpha = 0.9; % Set's transparency of the grid.
% Set x and y font sizes.
ax.XAxis.FontSize = 15;
ax.YAxis.FontSize = 24;
% The below would set everything: title, x axis, y axis, and tick mark label font sizes.
% ax.FontSize = 34;
% Bold all labels.
ax.FontWeight = 'bold';
hold off

Does anybody know of a straight-forward way to adjust the distance between the tick labels and their ticks?

In other words, to push the tick labels closer to the axis line.

You could turn the text labels off and then make your own tick labels with the text() function and place it wherever you want.
