I would like to change the cursor, like in Terminal, from the block to the I-Beam cursor.
How would I do this?
Also, on a side note, how do I change the color of the cursor?

Cursor type can be set for a given buffer (using buffer-local variable
cursor-type), as indicated in the answer by @King. (That answer uses
setq-default to set the default value for all buffers.)
Or it can be set for a given frame, as frame parameter
You can set it the default cursor type for all frames by adding it to option
default-frame-alist. For example add this item to the alist:
(cursor-type . bar).
Here is a command (from library oneonone.el) to set the cursor type for the current frame:
(defun 1on1-set-cursor-type (cursor-type) "Set the cursor type of the selected frame to CURSOR-TYPE. When called interactively, prompt for the type to use. To get the frame's current cursor type, use `frame-parameters'." (interactive (list (intern (completing-read "Cursor type: " (mapcar 'list '("box" "hollow" "bar" "hbar" nil)))))) (modify-frame-parameters (selected-frame) (list (cons 'cursor-type cursor-type))))
Cursor color is always per-frame, not per-buffer.
oneonone.el you will also find options to automatically change the cursor type when you switch a buffer between read-only and writable, or between overwrite mode and insert mode, or to change the type to a box cursor (more noticeable) when Emacs is idle.
