Want to get the terminal back to bryce@macbookpro instead of bryce@machine and have the 'ls' command only show visible files and folders.

It looks like you have some alias defined. Find what it is by running:
alias ls
This must be defined somewhere in what of the startup scripts of your shell. For example in case of Bash, you could find the list of fils to look at in the FILES section near the end of man bash:
/etc/profile The systemwide initialization file, executed for login shells ~/.bash_profile The personal initialization file, executed for login shells ~/.bashrc The individual per-interactive-shell startup file
To temporarily bypass the alias, you could run command ls or \ls, or temporarily remove the alias with unalias ls.
