Your budgies are very cute. After seeing your other thread, I believe you've ordered them a larger cage which will be very good for them.
I think the very best advice anyone can offer is for you to read through all of the How To Guides, the FAQs and the stickies located at the top of each section of the forum. You'll find most of your basic questions are answered after you've read through all of them.
I'm looking forward to hearing all about your budgie and hopefully seeing some pictures soon!!
