1. Go to the download links on your phone's browser and download to the phone, then set your market settings to allow non market installs (if possible), open your downloaded file(s) (apk's) and install.
2. download the files to your computer, connect your phone to your computer, transfer the files to your phone, on phone use a file manager to get to the files, same market sttings to allow non market installs, and install.
These two were broad general instructions, but I kept it basic, as I don't have your particular phone. But I'm sure others will chime in as well.
