    specs = th.newTabSpec("tag1");
    specs.setContent(R.id.tab1);
    specs.setIndicator("", getResources().getDrawable(R.drawable.b_news));
    th.addTab(specs);

    specs = th.newTabSpec("tag2");
    specs.setContent(R.id.tab2);
    specs.setIndicator("Library");
    th.addTab(specs);

Answer 1

    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    params.weight = 1.0f;
    params.gravity = Gravity.CENTER;

    mTabHost.getTabWidget().getChildAt(0).setLayoutParams(params);
    mTabHost.getTabWidget().getChildAt(1).setLayoutParams(params);
    mTabHost.getTabWidget().getChildAt(2).setLayoutParams(params);
    mTabHost.getTabWidget().getChildAt(3).setLayoutParams(params);

Answer 2

The answer was in the links I provided. I just needed to look a little bit more into it.
