I heard that when affiliates "mask" url, it is better from the search engine perspective. It is less likely that my keywords will become inactive as google adword does not see this as a link to affiliate site. Is this true? Please explain.

I want to build a site but only have small inventory. So I want to add Flash banners from affiliates and adsense then sell my stuff on a seperate area with google check out or paypal. Also I want to create my own widets to move around site and ad to other sites/blogs/ebay. I guess what I need to know is. Dose Yahoo store builder have tools to make flash and add code. How do you like it ?
Thanks all

Long time I am searching to set, design and start private business online, I had no idea, but little very little I start to set my web with some of free readymade disign web site to make my own. It sounds good! But, after starting, setting my pages, I found out that I have no idea how to attach and show or sell any product in my site, I have received many emails include many products for saling, Sure those for whom like me that has their private websites and not by any way related to a big store as ebay or google or…..etc. In the mean time, by any way I will proceed, after showing the products or my services, how can I received my money , by another word, what will be the steps with whom and how the financial operation will be completed?,

As suggested by friends that affiliate marketing ads can be published with Google adsense, But I am not sure that which affiliate marketing is the best and Genuine and Don’t conflict with Adsense.
