New Legend owner: to-do list, hoping for input

[rollmo]

Already found tons of invaluable info on this forum, and am excited to be a Legend owner. Just purchased a white 94 L Sedan, only 89K miles, and can't wait to get started. I put together a to-do list based on the threads I've read so far. Listed in order of priority from highest to lowest:

1. BHG/SHG modified leakdown test
2. EGR cleaning, EGR intake manifold replacement w/ RL part (better one w/ baffle)
3. Timing belt/water pump replacement
4. Brakes/rotors
5. Driver front door window tightening & seal replacement (window whistles, drives me crazy)
6. Leather replacement (several tears, top of back seat completely destroyed by sun)
7. Sound system upgrade (Bose speakers all blown, sound like crap)


I have more on my list, but this is the most pressing stuff IMO. Thoughts? Suggestions?

And, assuming I do have BHG or SHG, is it even worth doing the other engine stuff? Should I just do a swap instead? After reading lots of threads, I still am not clear on how "bad" a SHG is. If it's only seeping slightly, is it a huge worry? Replace right away? (That's probably a stupid question, but humor me anyway- I'm a newbie )
