Office building rehab questions - Sign, Lighting, Wallpaper

[Adam Craig]

Just closed on 1852 historic office space and we are starting rehab. ITs 4-6 different sized office units that will most likely house businesses like CPA, Attorney, Graphic design. I am going to keep the character but want to brighten it up - it needs it! The plan is to paint,carpet, improve lighting, landscaping, and possibly replace the sign for starters. 

Can you review pictures below and give me your thoughts on 

• 1. The sign.  Should we clean it up with paint and keep it? 
• 2. Lighting - Its florescent lighting - I want to go brighter bulbs for sure but should I upgrade the lights themselves?
• 3. Wall paper - The plan was to remove all of it and paint grey walls with white wainscoting (already there). Most of the wallpaper needs removed its old and stained. But any sense in keeping it where its in good shape? I dont like it but wanted other opinions.

In our commercial rehabs when we are upgrading the old T8 fluorescent lights we typically leave the fixtures in place, replace the ballasts and go with LED bulbs.  Huge cost savings.   

 Thanks for the tips. I am probably overthinking it but I've been reading up on fluorescent bulbs and I think you're right LED is the way to go. I initially thought replace everything with can lights but same-day expense might not be worth it since there are already a decent amount of can lights in the office. There are so many bulbs these days do concern yourself with not bright enough or too bright? I assume the ones that say daylight are appropriate
