I'm making use of the Wix standard dialogs. How do I customise the text of the messages displayed?
For example, in the License Agreement page, I want to change the text "I accept the terms in the License Agreement" to "I acknowledge and accept the terms of the above agreement."

How can I set at runtime the text to be displayed in VerifyReadyDlg ?
The chapter Advanced WiX Topics -> Wix UI Dialog Library -> Customizing Built-in WixUI Dialog Sets in the WiX documentation (wix.chm) has all the information on customising the UI dialogs, including the text. There's also a topic on customising the UI in the WiX tutorial at http://www.tramontana.co.hu/wix/ .
If you do find you need to override more of WiX's default behaviour, the best way to start is to download the sources ( e.g. from http://wix.sourceforge.net/releases/3.5.1030.0/wix35-sources.zip ): all the UI dialogs are in src\ext\UIExtension\wixlib, and will give you an insight into how it works.
