You can spend a lot of time mucking around to make a document look good - and sometimes fail. Starting with a good template is always a good idea - so you are using the correct styles from the start, and the fact it looks good will give you confidence you're making progress before you've even started adding content!
Rather than share my own templates, I'll share some sites which have templates:
- Docstoc - Contains documents, forms templates, papers and presentations... claims to have over 3 million documents, and some of them really good quality!! The browsing interface is great and after free registration you can click "download document" at the top and open in PDF/MS Word/MS PowerPoint etc (*****)
