Sounds like you've got a lot of excitement ahead! Be warned - it's a very addictive sport
So - firstly, rucksacks. There's loads of really good rucksacks out there so I'll recommend one I've used extensively and been really impressed with - the Lowe Alpine 'Alpine Attack'. Accessibility to this model is a little lower as it's been replaced with the 'Alpine Ascent which is similar but I haven't personally used - although it has good features such as bottom access and attachment methods for axes, poles etc for when you get more technical and out in winter.
When it comes to harnesses, I recommend a durable, slightly heavier harness - this may not be as lightweight as some models, but means that it will go the distance when doing lots of scrambling in potentially wet weather, getting dirty and scraped as you move up to grade 3/V Diff and start tackling short sections of bridging/easy climbing. It also increases comfort for all-day wear. Something like the Black Diamond Momentum is cheap but will perform well.
As for shoes, I'm always a massive advocate of try before you buy, especially for first pairs when you're starting out - it's important to remember that climbing shoes will feel very different from normal shoes, and whilst you should not feel pain, a very minimal level of discomfort/'odd feeling' is to be expected - this is simply due to your feet being unused to being contacted fully by the shoes. After a few months your feet will desensitise and your first shoes will start to feel like slippers - which is what you want for easy climbing/scrambling! As mentioned by Offwidth, a thin pair of socks can make the world of difference at first.
As mentioned above when it comes to beginner shoes there are a good selection across all the brands - but three I'd recommend are the La Sportiva Tarantula, the Scarpa Velocity V and the Red Chili Durango VCR. All of these three use harder wearing rubber and have simple velcro fastenings rather than laces, making them great for intermittent use on rock and also for building up your skills in the gym, whilst maintaining a good balance of performance for a beginner shoe.
Have fun scrambling!
