There are several other "survival phrases" you need to know to get along. Use the search function to find Spanish phrases, survival Spanish, useful phrases, online translators, etc.
I recommend printing out a custom list of standard phrases that work for YOU. Imagine scenarios and develop phrases based on those scenarios. Examples include asking for something at the pharmacist, in a tienda (shop), or albergue, hostal or hotel, arranging taxis, making a reservation, asking for medical help, etc.
I continue to try to improve my spoken Spanish as the staff at the Pilgrim Office want me to work on Compostelas when I work as a volunteer again this coming summer...yikes! That will require engaging in a sort-of-interview. I am comfortable if people "stick to the script." I can ask the usual questions, expecting the usual answers in return. But if they "go off script" talking about their families, what they saw, and what they did, I will be lost. So, I am a work-in-progress. Here's hoping...
I have found online Spanish dictionaries and translators for my iPod, and now my iPhone, very helpful. Over several years, I have accumulated a body of phrases that have worked for me. Some are worded to show to someone, like a pharmacist or hostal clerk to ask for help. Others are intended to be spoken simply without engaging in a long dialog that I cannot hope to hold up my end in.
I hope this helps the dialog.
