I open a text message to respond and my screen freezes

Question

I keep getting the "low on space" message pop up, and when I went to open a text message it would tell me that there is not enough space and I need to delete apps. I deleted some works in the text dictionary and then suddenly my phone started to act up. It wont let me delete blank works in my dictionary. Also, when I go to open up a text and respond I type in one letter and my screen freezes. When I finally get it to the home page the keyboard is still there and is making everything slow and or not work. I have to keep turning my phone on and off. I have already taken out the battery 3 times already and let it sit. 
Anyone have advice on what to do??? 
I don't want to have to do a factor reset because I am scared I will loose my calendar appointments, pictures etc.

Your internal storage is getting too low. These phones require a little bit of maintenance from time to time.
Check your internal storage. Settings > sd card & phone storage
Clear cache from the applications. Settings > applications > manage applications > all tab > menu button > sort by size. You will have to go through the apps one by one and pressing the white clear cache button. Browser, market and games seem to be the usual suspects.
Backup your text messages to the sd card or send to an email address. Search the Market for sms backup. If you want to save mms messages, you will likely have to choose a paid application.
After you have backed up the text messages, delete as many threads or individual messages as you can stand.
Clear call history. Not sure if there is an application that will back that up for you. I use Lookout which has that as option.
Move what applications you can to the sd card. The steps will be similar to the clear cache steps above.
After completing all that go back to get your internal storage level and hopefully be amazed how much space you have gained.
