The amsart document class has a very strict way in which it sets things up, specifically because it is meant for publication submissions. As such, there's not much in terms of user-interface variation available. This is a good thing. However, it requires a complete revamp of the ToC-generation and interaction in order for it to be flexible.
Here is something that seems to satisfy all your requirements without using any additional packages (except etoolbox):
\documentclass{amsart}
\usepackage[showframe,paper=a5paper]{geometry}% Just for this example

Specific to the requirements:
This is the default setting under amsart, so there's nothing to be done in this regard.
Only the \subsection and \subsubsection ToC entries have been adjusted to include a dotted line. This was taken from latex.ltx's \@dottedtocline that uses leaders.
Adjustments to the spacing between the dots can be achieved using (for example)
\makeatletter
\renewcommand{\subsection@dotsep}{5}% Adjust subsection dot gap
\renewcommand{\subsubsection@dotsep}{5}% Adjust subsubsection dot gap
\makeatother
The default values for both are 4.5.
The indentation can be set for each of the section levels \section, \subsection and \subsubsection, in addition to the width of the numbers in the ToC. The following self-explanatory macros set the defaults:
\makeatletter
\settocsectionnumwidth{2em}
\settocsubsectionnumwidth{2.5em}
\settocsubsubsectionnumwidth{3em}
\settocsectionindent{1pc}%
\settocsubsectionindent{\dimexpr\@tocsectionindent+\@tocsectionnumwidth}%
\settocsubsubsectionindent{\dimexpr\@tocsubsectionindent+\@tocsubsectionnumwidth}%
\makeatother
The subsection and subsubsection indents are set relative to the sections and subsections, making them line up within the ToC as required.
The default \@tocline macro of amsart provides a vertical skip before every sectional unit. This has been customized and can be set with a number of user-interface macros. The defaults are:
\settocsectionvskip{10pt}
\settocsubsectionvskip{0pt}
\settocsubsubsectionvskip{0pt}
This leaves a gap of at least 10pt above a \section heading, but no gap (0pt) above a subsection or subsubsection.
See (4) above.
This can be adjusted using the number widths as refined in (3) above.
See (6).
\contentsnamefont holds the formatting of the ToC heading. A simple \renewcommand suffices to changes this. For example,
\renewcommand{\contentsnamefont}{\bfseries\Large}
Each sectional heading in the ToC can be formatted at the "number+title" and "page number" level via the following self-explanatory macros:
\settocsectionformat{\bfseries}
\settocsubsectionformat{\mdseries}
\settocsubsubsectionformat{\mdseries}
\setsectionpnumformat{\bfseries}
\setsubsectionpnumformat{\mdseries}
\setsubsubsectionpnumformat{\mdseries}
(Optional) Insert \tocpagebreak within your document at the appropriate place between sectional units where you want the equivalent location to be broken in the ToC.
(Optional) \tableofcontents can be adjusted to insert a negative \vspace where appropriate.
This adaptation is not compatible with hyperref, unfortunately. If that is required, one may be better off by recreating the ToC and sectional unit layout using packages that support this in a more consistent/uniform way, and using a different class like article.
The following seems to be what you're after:
\documentclass{report}
\begin{document}
\tableofcontents
\chapter{A chapter}
\section{A section}
\subsection{A subsection}
\section*{Appendices}
\addcontentsline{toc}{section}{\bfseries Appendices}
\renewcommand{\thesubsection}{\arabic{subsection}}
\setcounter{subsection}{0}% Restart subsection numbering
\subsection{First appendix}
\subsection{Second appendix}
\end{document}
If you're using hyperref, more work needs to be done to accommodate for the referencing.
If you have more document content following the \chapter that contains your appendices, then you may have to restore the \subsection numbering. You can add
\renewcommand{\thesubsection}{\thesection.\arabic{subsection}}
before that content.

The
amsartclass indeed has the feature that if the argument to\subsectionis empty, then the number is printed boldface, while normally it is medium series.I don't like this feature at all, personally. However, what happens is that the code in
\@sectthat does the job is (line numbers refer toamsart.cls)but when
hyperrefis loaded, the argument#8isso it is not empty as far as
\@ifemptyis concerned.Here's a patch for it.
Actually, there is a bug in
amsart: if you have one subsection with empty title, all subsequent section numbers are typeset boldface.In order to cure this bug another couple of patches are needed:
