At this project my work was to migrate all old entries from a Mambo system to WordPress and create an unique theme. You can see the result here:
animal-public.de.

For the theme the YAML framework was used and these plugins:

• Contact Form 7 with Really Simple CAPTCHA
• Exclude Pages from Navigation
• Iframe
• Joomla/Mambo To WordPress Migrator (migration)
• Newsletter
• Post Type Switcher (migration)
• Quick Cache
• Regenerate Thumbnails (migration)
• SpeakUp! Email Petitions
• Velvet Blues Update URLs (migration)
• WP-Paginate
• WP Realtime Sitemap

jQuery

• jquery.easing.js / jquery.easing_compatibility.js
• jquery.elastic.js
• jquery.label_over.js
• slides.jquery.js
