Well, there are two solutions I can see. First, you could simply ignore
the sudo thing and use your commands after becoming root using 'su'.
Another one is to add your aliases to the adminstrative user aliases
(/home/whatever/.bash_aliases). If you do this, however, you must change
your aliases by adding 'sudo' in front of them. Beware that for multiple
commands (such as the above examples) you must either add sudo in front
of each command, or execute them all in a subshell: 

alias xpa+='sudo sh -c "mount -t vfat /dev/hda1 /mnt/da1;\
                        cd /mnt/da1; ls -aF'"

Hope that helps
