-Keyword: Keyword, Keyword, and much more?

Is this ok?

Greetings!
Please excuse me if this has been covered before, however I have not seen it as it is rather specific to a software issue.

My current software did not allow for ever changing metas. So I implemented a program that would allow for this. My knowledge of php is limited however everything seems rather backwards and I am trying to work around this to the best of my ability so I am requesting the opinions of others as to the viability of my TITLE meta.

I have approximately 8 keywords that I would like to target on a Ecom site. The 'big 3' I am also targetting are VERY high searches per month. So in order to get these into my title I have it listed like this do to software limitations.

First page options:
1. -Keyword1, keyword2, keyword3, keyword4, and much more.
2. .:keyword1, keyword2, keyword3, keyword4, and much more :.
3. (some starting character to seperate the category or subsequent products such as - or .:) Company Name Keyword1, keyword2, keyword3, and much more.

--The above is the absolute and remains throughout ALL pages. So if I do not do a beginning - or .:, what will happen is if you goto a category or product it will look like this Keyword4Keyword1, Keyword2 etc etc.

Subsequent pages (the above trails behind everything so that when you goto a category or product, that is placed first)
1. Keyword 4 - Keyword1, Keyword2, Keyword3, Keyword4, and much more.

Also I know that most of my competition has a rather entensive array of keyword stuffing in their titles, while some do not. It does not seem to affect them. I am targetting very high search keywords. So my questions are basicaly.

-Is a character before a keyword going to be ignored or lessened in value?

-If you put a company name before a keyword without a comma does THAT lessen the value?

-ANd which is the best format?

Thanks guys.
