New to the Passport Community.... Some questions...

Ok so like I said I am new to the Honda Passport community. Today I purchased a 1998 Passport. So far love it! But there are some issues I knew of when I bought it that maybe you can help me figure out. First, the back windshield wiper does not work. I dont even know where to start with that. Also, the front wipers have 3 speeds and only 2 work. The slowest speed doesnt work it just turns it off. And the last thing so far that I noticed, I think I can fix it but maybe someone has another idea, when I hit the gas, the gas pedal sticks. Like I can;t press down and I have to keep hitting it and then it clicks. The seller lubed it under the hood and loosend a screw and it fixed it a little so I think I have that figured out. Last thing. Where can I find some good not too expensive parts? I need like interior light covers and such. I would like floor mats and I want a trim kit because the trim isnt in great shape. Other than that it really is nice. If anyone can help me I would really appreciate it!

Thank you and I look forward to this!
