Converting a C++ project to OpenTK, can't find certain calls

Hi, I am new here

I am converting a C++ project to a C# Class Library that is using OpenTK 1.0
I am using VS2010 and have all the frameworks load into the system.

I am converting the code, but have trouble finding the OpenTK equivalant for some parts which are marked with arrows:

bool Base_OpenGL::SetupProjection(int width, int height)
{
if (height == 0) // don't want a divide by zero
{
height = 1;
}
m_Zdelta = (height/2)/(tan(FovY/2));
// \/ zoom factor
//m_Zdelta = m_Zdelta * 2.45;
glViewport(0, 0, width, height); // reset the viewport to new dimensions
glMatrixMode(GL_PROJECTION); // set projection matrix current matrix
glLoadIdentity(); // reset projection matrix
// calculate aspect ratio of window
gluPerspective(FovY,(GLfloat)width/(GLfloat)height,200.0f, 2000.0f); <-------------What is the OpenTK equivalant here.
glMatrixMode(GL_MODELVIEW); // set modelview matrix
glLoadIdentity(); // reset modelview matrix
//load window dimensions into class memory
m_windowWidth = (float)width;
m_windowHeight = (float)height;
return true;
}

unsigned int Base_OpenGL::CreateBitmapFont(wchar_t *fontName, int fontSize) <--------I'll need help on this whole function
{
HFONT hFont; // the windows font
unsigned int base;
//char *cfontname;

base = glGenLists(96);
//WideCharToMultiByte(CP_UTF8, WC_DEFAULTCHAR, fontName, -1, *cfontname, sizeof(*cfontname), NULL, NULL);
//wcstombs();
if (!_wcsicmp (fontName , L"symbol"))
{
hFont = CreateFont(fontSize, 0, 0, 0, FW_NORMAL, FALSE, FALSE, FALSE,
SYMBOL_CHARSET, OUT_TT_PRECIS, CLIP_DEFAULT_PRECIS,
ANTIALIASED_QUALITY, FF_DONTCARE | DEFAULT_PITCH,
fontName);
}
else
{
hFont = CreateFont(fontSize, 0, 0, 0, FW_NORMAL, FALSE, FALSE, FALSE,
ANSI_CHARSET, OUT_TT_PRECIS, CLIP_DEFAULT_PRECIS,
ANTIALIASED_QUALITY, FF_DONTCARE | DEFAULT_PITCH,
fontName);
}

if (!hFont)
return 0;

SelectObject(hDC, hFont);
wglUseFontBitmaps(hDC, 32, 96, base);

return base;
}

I got DeleteFont made and converted, but not sure if I got Render font right.

protected void RenderFont(int xPos, int yPos, uint basef, string str) //create font for openGL
{
if ((basef == 0) /*|| (!str)*/)
return;

GL.RasterPos2(xPos, yPos);
GL.PushAttrib(AttribMask.ListBit);
GL.ListBase(basef - 32);
GL.CallLists( (int)(str.Length * 2), ListNameType.UnsignedByte,IntPtr.Zero);
GL.PopAttrib();
}
