Delete content before a 301 redirect?

My old site page is mywebdomain/about-us.aspx and now i have moved to php+wordpress making the new page as mywebdomain/about-us/

I understand in terms of seo a 301 redirect is the best which means I will be doing 301 redirect:
mywebdomain/about-us.aspx -> mywebdomain/about-us/

Since content of both pages is same, should i delete the content from the aspx page or a simple 301 redirect is ok?

Or which is the best way?

No it doesnt matter. Once you impliment the 301 redirect the old page will no longer exist as far as google is concerned.
Google will understand right - old page has been removed and replaced by new page.
Google will expect content to be the same and no one will any longer be able to access old page anyway. they will be redirect straight to new page. So what is on old page is irrelevant.

Thanks. I have now done the 301 redirect from the cpanel.

Cheers!

What about links on my site?

Should I continue to let my pages link to the old page or change it to link it to the new page?

And any new links in create? (either on site or links from other site)
