In tkz-fct, the command \tkzDrawX draws the x-axis.
Is there an option to control the size of the ticks on this axis? Is it possible to draw the axis even without ticks at all?

Yes and you have an example in the documentation of tkz-basepage 14
An example
\documentclass{scrartcl}
\usepackage{tkz-fct}
\usetkzobj{all}
\tikzset{numline/.style={%
label={},
right space=2.5,
left space=0.5,
line width=1pt,
tickup=5pt,
tickdn=0pt}}
\tikzset{xaxe style/.style={>=stealth',<->}}
\tkzSetUpMark[mark=ball,size=4pt]
\tikzset{mark style/.style={inner sep = 0pt,
mark = ball,
mark size = 4pt,
ball color = red}}
\begin{document}
\begin{tikzpicture}
\tkzInit
\tkzDrawX[numline]
\tkzLabelX[step=10]
\tkzHTick{3}
\tkzText[below=3pt,blue](3,0){3}
\tkzHTick{7}
\tkzText[below=3pt,blue](7,0){7}
\end{tikzpicture}
\end{document}

\tkzSetUpColors[background=fondpaille,text=Maroon], this macros is defined in tkz-base. But you can modified\def\tkz@backgroundcolor{white}or you can change a stylexlabel styleand finally I think it's possible to change\tkz@fillcolorbut I'm not sure for the last idea – Alain Matthes May 31 '11 at 20:09
