sei was right, CCS is the only TI IDE, based on Eclipse and, then, Java. I think it isn't so much easy for beginners: a lot of configuration feactures (too much and sometimes redundant), slow and some small bugs.
Often it stalls due to Java/eclipse and, if you use the low-cost jtag emulator (xds100), it can result very slow and chashes Windows (the classic blue window).
For the Texas devices, the website is full (crowded) of documentation and links that you risk to lose yourself. Sometimes the google search is better.
