MacOS – When I open a minimized window, I don’t jump to the space it opens in

You can create a new service using automator (from the applications folder). At the top of the automator window, enter: Service receives 'no input' in 'any application'. Then, in the workflow, add 'Run applescript'. Make the applescript contain the following:

on run {input, parameters}

    tell application "Terminal"
        do script ""
        activate
    end tell

    return input
end run

(You can add any command you like into the do script line between the " " (e.g. something useful to run when terminal first opens like uptime if you like, or just leave it blank).

Save the service as 'Open Terminal' or whatever name you like. It should now appear in your services menu.

Then if you want to add a keyboard shortcut, you just need to go to System Preferences -> Keyboard -> Keyboard Shortcuts tab, select services in the left hand menu, and find your new service (its probably near the bottom). Just click in the space to the right of your service name, and assign it whatever keyboard shortcut you like, and hey presto! it should all work

This will help users running Lion but won't solve your problem in Leopard.

In Lion, there is a Control Panel setting under Mission Control that says When switching to an app, switch to a space with open windows for that app. Deselect it. Note that when this option is deselected, if you click an app in the Dock with open windows in another space, on the first click you will get your desired behavior, but if you click the icon in the dock again, it will switch to the space currently containing windows for the app.
