Customer Account Page Layout Change

Question

Under my account page, I need to change the Account Navigation from left to right, along with My Orders block. My Account Dashborad will be on left side.

Also I need to add My Cart Block above My Orders Block.

For example:

My Account Dashboard                        My Account
                                            Account Dashboard
Recent Orders Block                         Account Information
                                            Address Book
                                            My Orders
                                            Billing Agreements
Account Information                         My Product Reviews
                                            My Tags

                                            My Cart Info
                                            My Cart Block

                                            My Orders Info
                                            My Orders Block

I tried changing the layout from 2columns-left.phtml to 2columns-right.phtml but its not working.

Also I have a blog extension with 2columns-right.phtml layout, so is it going to affect account navigation layout too.
