I presume you have searched and read about retrobrite here on 68K. Everything written there applies to the SE/30 equally. I believe JDW has actually done this on his SE/30.
Yes the gel is much more prone to splotching and uneven results, based on numerous reports. You should remove all metal from the case as there is a chance it will react corrosively with the H2O2. All other paper or plastic labels seem to fair well. Take-apart is self explanatory, but there are sources online someone should be able to point you to if you are unsure. Keycaps just pop off, but since the key stalks are old, you definitely risk breakage no matter how careful you may be.
Immersion offers a much more even and reliable process, though requires a much larger space for preparation, and more H2O2. One word of caution regarding what kind of EM coating is lining your SE/30. If you have the shiny, reflective type, instead of the flat gray, rough metallic paint, then you may need to stick with the gel approach as there have been some reports of this coating leaching off the inside of the case during immersion.
