I wish Rob Miller posted here cause I bet he'd have some good advice for you here, but alas. You're stuck with little old me.
Given you're only squatting 110x5 after "many weeks" I would say getting your form ironed out is probably very important. While you wait for that in person session in a month or two, post to the technique forum, or get verified and post a video here, so you can at least get a little help and improvement in the meantime.
In terms of programming, I'd say to cease altogether through the end of your properly run linear progression. I think you'll be pleasantly surprised how much stronger you are when you do that properly, WITH good form. At 6' and 200 lbs, you're already rather big for a climber, and at 61, you're not going to gain muscle mass as quickly as a 25 or even 40 year old, so don't go crazy and gain a lot of weight here. Get 200g of protein a day, and you should be able to add weight to your lifts in a properly run LP for 2-3 months.
After that, reintroduce climbing once a week for 4-6 weeks, then back up to twice, and you'll need to program around it. Hiring a coach for that may be a very good idea, given the competing resources for recovery, and your age.
Expect to be sore and disappointed the first 1-3 times back climbing, but once you're back in the swing of things, I would be surprised if you don't start noticing some solid benefits, provided you didn't do something stupid and try to gain 50 lbs on your LP like a 140lb kid needs to.
