In the current scenario, I would recommend any of these
1. SCJP + SCJD
2. SCJP + SCJD + SCEA
3. SCJP + SCWCD + SCEA
Choice between SCJD and SCWCD depends on which all technologies u r working on or which u want to work on in the future.
Servlets and JSPs are more in demand, and WCD is relatively easy.
SCJD will b relatively difficult but will will make ur coding / designing skills more robust, provided u love those technologies.
Whatever u choose, make u sure that u go r SCEA
