This is not a direct answer.
If you want to use `vim` to write your `latex` documents `latex-suite` isn't recommended anylonger, at least from my perspective. There are several more comprehensive vim-scripts which handle this task a lot better.

**LaTeX-Box**
In the case you want a lightweight environment and a fast learning progress you should try `LaTeX-Box`. The documentation is very legible and after a short period of time you know the important commands.
**Automatic LaTeX Plugin**
`atp` is everything in one at the expense of a rather steep learning curve and a bit bloated. The documentation is quite long and you need a bit of time for deeper insights.
Both scripts are at least a lot better maintained than `latex-suite` and have a mailing-list i.e. an issue tracker. So there is no need to stick with `latex-suite` anylonger.
