I'm agreeing with everyone above in just saying no to welcome pages. Remember the average web user has the attention span of a fruit fly. They need to get what they want fast and then leave. Rarely does anyone linger on a website anymore.
Your home page should be a snapshot of everything everyone might want to know about you if they don't want to dig too far. So it should have who you are and what you are - your name and writer of <insiert genre>. Then list your latest piece published. It should have contact information in this same area, but you should also have a page dedicated to your contact information. You're doubling up but you want something quick for people to find by your name, like an email address, and a more comprehensive contact page with your email and any other information you want known. You can include what you're doing now - if you don't keep a blog, giving readers a way to date your website is important. So if you include a sort of news section where you can say - I'll be at this conference on this date, this short story is released on this date, finished second round edits on the novel on this date, whatever. Static pages are static but your readers should still be able to grasp some information about what you are doing RIGHT NOW from it, even if you don't blog.
The static homepage should have a picture of you and a very easy, graphically pleasing way to search through your site for more information. A bio page, a contact page, and a separate page for each published, purchasable story etc.Your home page should also include all your social media links, up to date twitter feed, and RSS button. These should be PROMINANT, so don't stick them at teh bottom. In fact, they should be as close to the header as possible. Copyright info always goes at the bottom.
An author website is sort of like a resume. Information someone might want to know about you should be easy to find on the first page, because most people won't click further. Having a graphic of your cover art for your short story (if you have cover art) should be on this page as well, but you don't necessarily need to include how to buy it. If they click on the cover it should take them to a page dedicated to that short story with a synopsis, how and where to buy, and any blurb reviews or links to online reviews.
Do not include anything that is not relevant. If you don't want those articles listed on your site because they have nothing to do with your short stories or publications, don't include them. While the site is like a resume, it's not a resume.
And the best rule of thumb? Go to 5-10 author websites you like and compare and contrast what you like and don't like about them. Notice what similarities they all have. Emulate that. When it comes to websites, you really don't want to stray far from the norm. You don't want to stand out too much when it comes to the basics because readers will know how websites are supposed to work and if yours is designed differently, they'll be frustrated.
Also black or very dark backgrounds are pretty dated. Clean, bright websites are more modern and are easier to read from. Darker websites tend to be effective in certain media (like film when your graphics and video trailers are the center stage and you're emulating a dark theater). The website look should tie into what you write about though. It should remind the reader of the genre or storytype you write.
