Alan,
Your plan looks good..IMHO
you should also read the specifications for JSP and Servlet and try to remember the names of elements and their use within the <web-app> deployment descriptor tags... remember this
test is marginally easier than the
SCJP so you may try to buy any one of the commercial exams (though there is no harm in buying both, its a question of money). There are many mock exams available for free to practise including one in this web site and many others are being made available by fellow ranchers. You can always clarify any doubts you may have in this forum....
All the best...you can do it...go for it...
