Who can I bring to a disciplinary hearing?

A work colleague or a trade union representative. You do not have a statutory right to bring a solicitor, though some employers allow it in serious cases.

What if the outcome is a dismissal?

You should appeal in writing within the time frame stated in the outcome letter. Any tribunal claim for unfair dismissal must be started within three months less one day from the effective date of termination, and internal appeals do not stop that clock.

Can I be dismissed for a first offence?

Only for gross misconduct, and only after a fair investigation and hearing. Otherwise, dismissal is normally reserved for repeated conduct after warnings.
