Is there a good resource for getting started with LISAEM - I have 2.0 downloaded - but want to create a workspace (ProfileHD) that has the LOS and Pascal Workspace - but not sure where to start or if someone has already built an image like that - I can't even get pass the boot rom - I tried downloading the ROMS from the Macintosh Repository but it keeps crashing.. Not a great start.

I recently wrote this article, which may help you:
https://github.com/arcanebyte/lisaem/blob/master/LisaEmAsASoftwareDevelopmentEnvironment.md

It suggests that you can download and use the "H" ROMs from https://www.macintoshrepository.org/articles/626-how-to-install-the-original-boot-rom-for-lisaem , but I , in fact, have not verified that they work. I will do so tomorrow...

Note that some of the info on this page (like the Pseudo TTY setup) will  not work with v2.0. You will need to download the last "continuous" build from https://github.com/arcanebyte/lisaem/releases.

I followed the instructions at https://www.macintoshrepository.org/articles/626-how-to-install-the-original-boot-rom-for-lisaem

They end with Step 6 - After Setting Lisa ROM as boot.hi apply and restart LisaEm.

This produces a file named boot.ROM in the same folder (it combining files boot.lo and boot.hi into one).

So there is one final step needed:

Step 7 - Once you restart LisaEm, open again File->Preferences, set the Lisa ROM to file boot.ROM, apply.

Now you can start the emulation, e.g. from the Key->Power Button menu. You should see a brief power-on-self-test, and then a screen for choosing where to boot from.

I tested it on Linux, but it should work on other platforms, too.

The ROM files are also available for download at https://www.bitsavers.org/bits/Apple/Lisa/firmware/ .

Thank you for the help.

Has anyone successfully created a profile image with LOS and a PASCAL workspace?

It seems that you have passed the ROMs hurdle! Good.

Yes, both LOS1+Workshop1 or LOS3+Workshop3 can be installed.

For LOS3 it goes like this: Use an "H" Rom (recommended) and "A8" i/o rom.

Leave the "disk image" in File->Preferences empty. Restart LisaEm and it will prompt you to create a new empty profile image file. Choose e.g. "10MB". Apply and restart.

At the Lisa boot menu, go to File->Insert diskette and "insert" LOS 3 installation floppy disk 1 image. Click on the" floppy disk" icon to boot from it and follow the instructions. When prompted to wipe out the profile drive, say "yes".

Finish the installation, restart, then click on the "ProFile" at the boot menu to boot from it. You are in LOS3. Good.

Restart, then at the boot menu insert the Workshop installation disk 1 and boot from it. When prompted, do not wipe the Profile disk (it would wipe out the LOS installation). Finish the installation, reboot.

At the boot menu, choose to boot from the ProFile. You shall see the "environment selection" dialog, where you can choose to boot LOS or Workshop. If you don't see it, reboot again, and press any key while booting; it will show you the dialog.

LOS and Workshop share the same disk volume, but LOS is hiding all files from the user, and showing you only what Apple wants you to see. So if you develop/compile a new LOS application in Workshop, you shall see it once you reboot into LOS (this is just an overview of how the development process works).
