Metatags Take Up 2 Much Space?

[SPARKO]

I dont know whether it was Morgan or someone said it that a lot of things on a general meta tag can take up too much space and are now irrelevant with Search Engines.
So my meta tag currently looks like this:

<title>Web Design Wales - Web Page Design and Computer Sales</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta name="description" content="Computer Sales and Web Design Wales budget-tech.co.uk. Based in Wales UK. Web Design and Services based in Wales. Web page design for business Wales">
<meta name ="keywords" content ="Budget Technology, budget-technology.co.uk, web page, services, business, web design, website, Internet, bespoke, programming, maintenance, computer, leasing, laptop, printer, server, sales, Wales, UK, based">
<meta name="copyright" content="budget-tech.co.uk ">
<meta name="robots" content="INDEX, FOLLOW">
<meta name="revisit-after" content="30 days">
<meta name="rating" content="General">
<meta name="author" content="http://www.budget-tech.co.uk">
<meta http-equiv="reply-to" content="enquiries@budget-tech.co.uk">
<meta name="language" content="english">
<meta name="generator" content="BBEdit 7.0" />

so should I cut out the copyright, revisit after, rating, language ? Im sure I was told before that some have weighting like author cos its a link, reply to again similar so should I cut these out ? Perhaps its a suck it and see scenario.
