help patching apis

Hi all,
to write a tool of mine, I'm searching for infos on how to patch these apis/structures..

-Hide NtGlobalFlag
-Hide ProcessHeapFlag
-Patch ZwQueryInformationProcess (==patch UnhandledExceptionFilter)
-Patch ZwSetInformationThread
-Patch CheckRemoteDebuggerPresent
-Patch OutputDebugStringA

Detailed infos (how to patch, when, what where) are welcome! If some info is not good for public tell me and send it to me by PM, I will guarantee to not spread it!

At least these are almost all I have knowledge should be patched, I already don't know how to do.

10x in advance for anwers..
